Seth’s been busy - he recently added channels (sort of like customizable über-categories in Conversant) for people he blogs about, including one for Steve Ivy - neat! If he’s mentioned you and there’s a category for your name, you can also subscribe to a vanity feed (linked on the channel page).
You can also get crazy with the search interface built into the weblog.
Here's an rss feed that lists items which mention both steve and jim. (Note that it could be any steve or jim, and oddly I have two pairs of friends with those names.)
