ivan has been around this community for quite a while- he was one of the people who built tipjoy, and his move to facebook was much discussed. perhaps he assumed people would know.
Also, clicking on his username indicates this clearly (at least now).
I didn't think I was expressing opinions about facebook, just bringing up things that others have brought up.
I probably should have mentioned I work at facebook and all comments are my own - mainly to insulate myself. I just added this to my news.yc profile "[every comment on this site is my own opinion, and not that of current or past employers]"
I think it is silly to suggest as some have that every comment requires a caveat. The comment replied to Paul Buchheit, also at facebook, who made no caveat. My profile is a click away, as is google http://www.google.com/search?q=ivankirigin
People get overly sensitive about this. I don't think my employment changes my original comment at all.
