Well, Jason Calcanis (formerly the guy behind Silicon Alley Reporter and now the guy behind Weblogs Inc) has just announced OnlineAdvertising 2005. I went to one of his Wireless Conferences in NYC years ago, and other than Gnomedex, it was easily one of the best that I have attended.
OnlineAdvertising 2005 seems pretty cool:
200+ attendees (nice and intimate like Gnomedex)
Invite only (like TED Global – which Ace says was outstanding this year)
In LA (a city I kinda like which has a bunch of my clients)
Seems pretty cool. Will be interesting if I make the cut.
