i was a part of the team that bought GeoCities at Yahoo, and i think it wasn't as dumb of a deal as it looks on paper, because a) YHOO stock was so high at the time that the $3.8B wasn't actually all that dilutive, and b) buying GeoCities ensured Yahoo was the #1 destination online, and thus we could command a disproportionate share of ad revenue. If you wanna look at a really silly deal that Yahoo did, how about the Broadcast.com deal? Billions for a bunch of servers...
