According to a new Nielsen Online report, Facebook now has a 47% reach in the UK, the Guardian reports. Together, member communities (made up of blogs and social networks) are the fourth most popular web destination in the UK - ahead of personal email. They’ve grown over 10% in the last year.

However, UK penetration is dwarfed by Brazil - the Google owned social network Orkut has a 70% penetration there, the highest social network penetration of any of the countries in the Nielsen survey.

Brazil is also top in time spent on these sites - 23% of all time spent (1 in 4 minutes), followed closely by the UK with 17% of all time spent online (1 in 6 minutes).

This shows how far social networks have come in terms of personal use - however also points out that despite the seemingly world dominating growth of Facebook, it’s not the total solution if you’re aiming for a global audience.
