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.
