I've been following programmers that make stuff that I like, and programs that I use. Collectively, the news feed for all these follows have been pretty useful because it's a little bit like a leading indicator on what projects productive people find interesting, so you hear about things a little bit earlier. I found about about _why's Mixico a few days before it was posted here.

I've heard of most of the names top of the list, but #2 was pretty interesting. I had never heard of imbriaco, but it seems like he has just one project: the erlang-textmate. Seems like it's because 37signals follows him, so that gives a lot of juice to his rankings.
