Ask HN: Who do you follow on RSS?

I just switched to a new gmail address as part of an attempt to "clean out" my digital life. I've been migrating, cleaning out, deleting, and pruning everything I do to cut down on the fat and make my interactions with technology faster and more efficient.

So now I have a completely clean, 100% empty Google Reader. I'll be finding my own feeds to add, but wanted to get a solid start from people here.

So who are the most valuable people, blogs, or companies you follow on your RSS Reader?
