There is a lot of discussion going on about Facebook, FriendFeed, Twitter, and realtime search.

This is to be expected since yesterday it was announced that Facebook is acquiring FriendFeed. Hitwise has shared some data regarding FriendFeeds popularity in the UK. Its growing fast, and has increased by 180 over the last 12 months in terms of traffic. Its nowhere near what Facebook or Twitter get, but Hitwises Robin Goad says that visitors to FriendFeed are typical early adopters just the kind of people who were first to embrace Facebook, Twitter and a range of other social media success stories as well as quite few failures along the way!.
