Is the UK Networking or Wilfing?

The latest research from comScore finds U.K. social networking site usage to be the highest in Europe. Whilst the UK users average 5.8 hours per month (with the heavy users' average being 22 hours per month), the average hours per user in Germany is only 3.1 hours and in France 2.0 hours. There are two ways of viewing these result:
1) UK residents are using social networking sites to share ideas, collaborate, and come up with innovative ideas, and increased use of social networking sites will help economic growth.
2) UK residents are merely wilfing, aimlessly surfing the internet with little or no purpose (from the phrase 'what was I looking for), and is of little productive use.

Whilst the press release lacks details on which social networking sites are being used (LinkedIn use seems likely to be more productive than MySpace), I fear that the majority of use is likely to be the big three generic sites (i.e., MySpace, Bebo, and Facebook), and people's surfing habits have changed from aimlessly surfing the whole web to aimlessly surfing/interacting with their social network communities. Whilst I am sure that our fellow Europeans will soon catch up, I don't think it will be something that they'll be boasting about.
