You tell me:

How many of those companies do you recognize after a year...

I'd say:

Mint Powerset (though only because of permanent beta) TripIt (awesome!) Flock (for some, not me) Xobni

And with a decent effort, any of them would have been just as successful without TC40. (Though TC40 could very well have helped them quite a bit.)

Maybe it was a rhetorical question but xobni, mint and flock are the only ones I recognize and the only one I really use everyday is xobni. Mint is OK but I really only read the summary emails and don't log in often.
