Heather Dougherty at Hitwise has this interesting post on search vs social networking driving traffic to video sites: Search & Social Networks neck & neck for video referrals
It's obvious that search is on a trajectory that will soon surpass social. Some of this must be due to improvements in video metadata allowing it to be more easily found? Universal search might be another factor? I have to admit, however, that I'm mostly confused by this graph. A plausible explanation escapes me. Translation: This isn't what I would expect to see. Ideas?
