I wonder why we have to choose between services that only allow the author to tag posts and feed – like technorati – or services that mostly allow the reader to tag posts – like del.icio.us.

If those services use tags to add information related to the “aboutness” of the posts or blogs, then they should allow tagging by everyone – much as Flickr. And they should also allow users to suggest “related” tags.

When using a service like Technorati to alert people about stuff you wrote, the current setup works. Once you start using it to search for stuff, the limitations of having author-only tags and (I assume) system-only “related tags” become somewhat obvious.

Tagging is a very interesting emerging phenomenon, one that engenders many different applications. Some people people use tags to alert others that they have written something (Technorati tags are often being used that way), others use them like a folder organizing system to organize their saved bookmarks (i.e., Yahoo/del.icio.us), many use it to share and find web pages (i.e, del.icio.us, furl), photos (i.e., flickr), music (lastfm), videos (i.e., YouTube), or even dates (i.e., consumating), and some bloggers use it to annotate web pages for blog republishing purposes (i.e., del.icio.us). As a publisher, we are also trying to use it to help readers navigate through vast amounts of posts (i.e., Corante Marketing Hub).

Surely there are a ton of potentially useful and lucrative new usages of tagging which I am missing or which have not yet been tried. But then I came across 1000tags.com – which tries to use tagging for people to advertise their site. In their own words they are “a project that aims to put to the test in its simplest form the viability of tagging as a way to advertise, by presenting a tag cloud formed by tags added by people who try to promote a particular site or page.” The way they do it is by ” offering a web page where anyone can book a particular tag that will later be displayed in the main tag cloud at the 1000tags.com page, as well as allowing web site owners to add their tag – for free of course – by syndicating a small tag cloud at their pages.”

Maybe I am slow – and that surely has happened before – but somehow I do not get this one. Why would I list a tag cloud on my site that has nothing to do with my site? It does not help readers, and I am not sure how it would help me as a blogger (other than perhaps increased “google juice” “if” the tag I choose becomes really popular and “if” many other bloggers list the 1000tags.com tag cloud on their site). Plus there is only one tag cloud – which right now includes poker, sex, dating, ???, BBW – not exactly things that are related to this blog – but which might arguably be of interest to some readers

At any rate – just for posting your opinion about them you get a free tag. So I will submit a request for my free tag, and see what happens.

There is a great post on tagging at ZnetLady (via CorporatePR).

Recommendations go from the basic use of tags to pretty interesting ones involving remixing feeds, tagging your employee profiles and more.

Molly E. Holzschlag over at Molly.com has an interesting post on Technorati based on a visit she made with their technical folks (via what’s next blog).

It’s a very good post – talking about recent system problems, but most importantly about the effectiveness in search of using technorati tags.

I guess you can say that when a dating service starts using tags to tag people (here – via Tech crunch)

It is a hoot to look at popular and unpopular tags…

David Weinberger picks up on an older post from Tom Coates at Plasticbag on tagging – which leads to an interesting conversation over at many-to-many (disclosure – I accepted to join Corante as a partner – more on that later).

As a reminder – the original post posits that tags for blogs change over time for three reasons:

• the content changes
• people start using new terms (i.e., Ajax) to describe things
• it is a reflection of the fact that people tag differently – and that their tagging habits change over time (which I guess could also mean that your readership is shifting)

Tom further elaborates on that last point by identifying two different types of taggers – those that tag as an act of filing and those that use tags as annotations (much like when you tag Flickr photos).

David thinks that most people do both. They file (or folder) when they do it for themselves and they tag when they want to contribute to a social tagstream.

I agree with the fact that most people have multiple tagging behaviors depending on what they’re doing. But I also think that there are more than two tagging behaviors. Some do tag as an act of filing – that is very much how you use your categories on your blog or how some people use delicious or furl. Some do tag to let others know that they found something which might be of interest to them (as some do through delicious – knowing that others subscribe to a particular tag). Others use it to alert others that they wrote something that might interest others (much the way people use Technorati tags). And lastly you have those that use it to annotate something for re-publishing (much like people are using delicious tags to comment on something they see on the web – only to have it being re-published on their blog).

I guess you could lump the latter three together into one category – but for me they are different enough to threat as three distinct cases of tagging. The difference between the first and third behavior is also why I think it makes no sense for Technorati to pick up categories as tags.

There is an interesting new little feature over at delicious – although I am not sure I like it yet. It provides users with the ability to tag for someone else (here).

By now you know that I am very interested in this topic and that I believe that this is one of the potential cornerstones of making KM finally work. That being said there are a few interesting developments that crossed my aggregator today.

First – here is a great article on folksonomies vs. taxonomies that will be presented later this week by Emanuele Quintarelli (via coporate blogging). The author does a good job of explaining where taxonomies fit vs. where folksonomies fit. He also takes you through the good and the bad of folskononies and specifically addresses the use of it within the enterprise – citing as one of the benefits the bridging of silos within companies where the same thing sometimes goes by a totally different name.

That reminded me of a large medical devices company I used to work with. The terminology used for product innovation between the different product groups was so dissimilar that a product manager from one department simply could not be transferred into another! Talk about barriers to cross-product innovation…

IBM is also rolling out enterpise usage of folksonomies – check out James Snell’s post on that yesterday.

As you may have noticed (I know I am not the first), I am having del.icio.us post the things that I save to del.icio.us on my blog every day. That caused me to use delicious tagging differently than I used to.

In the past I would tag stuff at delicious primarily for my own use. Now I use it to bring stuff that if of interest to me, and which I think will be interesting to you as well, to your attention. They are articles and web sites that fit with what I am writing about but for which I do not have enough original commentary (delicious lets me add one line of extended comment – which I have to start using better). In effect its a little like the Technorati tags except that if the links are of interest to you you can tag them yourself and put your own commentary on it.

Tom Coates over at Plasticbag has another view of how different people use tags (here). Some use it as folders to organize their stuff while he uses it to annotate a post.

It’s really interesting to see how different people tag differently.
