I believe NickB is one of the FriendFeed guys, though I could be wrong. I remember a FriendFeed staff member going by FirstnameL, anyway.

Don't think he's FriendFeed, the whole FriendFeed team is listed on their website and there's no Nick:

NickB also said his startup uses a lot of Ruby on Rails, and Friendfeed's a mostly-Python shop.

PaulB, then? Hmm.

He's just "paul" on HN
