del.icio.us as a proxy for me

I'm giving myself 15 minutes to write an entry each day. This morning I was pondering what to write about, so I looked at my collected links in del.icio.us, presented in reverse chronological order, and was struck by the fact that it mirrors quite well what I'm working on at work, coupled with what I'm currently interested in.

(This is simply because I often bookmark answers to my own work questions, probably a common practice among software engineers.)

I think an excellent feature for del.icio.us would be a "tag stream", akin to David Galernter's Lifestreams, where your link tags would be clustered over time and you could get a sense of how your focus has shifted from topic to topic.

It would also be an excellent proxy for a resumé, or at least help you maintain one.
