I use del.icio.us for bookmarking sites that I want to remember, and I use a cool feature to post each day’s links as a blog post. A while back, I learned about the “for” tag in del.icio.us, where if you tag an item with “for:username“, that item appears in the “links for you” section for that user on del.icio.us, which they can also subscribe to in their RSS reader. In other words, you can tag a site using del.icio.us specifically for another person to look at.
Today, when I was tagging something, I noticed a new section in the tagging screen: usually there’s just “recommended tags” (how most other people have tagged this link), “your tags” and “popular tags”, but now there’s also “your network”, which lists the for: tag for each of the people who are listed as being in your del.icio.us network.
