"YouTube and Twitter were the fastest growing social networks in May, whilst market leader Facebook lost market share of visits for a third consecutive month. YouTube consolidated its position as the second biggest social network in the UK, accounting for 20.52% of all UK Internet visits to social networks during the month. Meanwhile Twitter had its biggest ever month of UK Internet visits, peaking on 21 May when the website accounted for 1 in every 184 UK Internet visits.
"The growth of YouTube and Twitter during May had an impact on Facebook’s market share, which dropped to 53.61% of all visits to social networks for the month. Overall seven of the top 10 most popular social networks in the UK gained market share of visits in May, whilst Facebook, Moshi Monsters and MySpace all lost market share."

- The fate of previous garden sites. Really Facebook is repackaging the same strategy AOL used 15 years ago. Give people a single location on the web where they have their friends and family on hand and are not exposed to the freaks and nerds that mix on a global scale. This strategy did not work for AOL and it is not clear why is should work now. It is interesting to note that people seem to be leaving Faecbook for the wild open spaces of YouTube and Twitter
- Don't dismiss privacy. Launching face recognition the way it did may have been a nudge to push significant numbers of fence sitting Facebook users towards Twitter and YouTube.
