It is time for the second annual TechCrunch Europe ChristmasCrunch! Yes folks it’s our annual TechCrunch Europe meetup and Festive Holiday party, in one handy package. This year we’re taking a different tack – basing it around one of the the hottest themes right now, namely the rise of realtime streams. We’ve seen the emergence of Twitter, Facebook, Friendfieed and Google Wave but it’s clear that this is only just the beginning of the world going realtime. TechCrunch is running the Realtime Crunchup of course, but this event in London will also feature some of the hottest realtime startups in the world today.
