Meaningful and detailed social networking statistics can prove elusive, certainly on the open net, so all the better to see a good summary of data from Facebook, MySpace and the lower profile Reunion on Jeremiah’s Web Strategy blog.

Perhaps the most interesting in the post is the Forrester prediction that Facebook will overtake MySpace in terms of registered users by end 2008. Feels about right until you look at the stats on display.

The stats claim 60m active users at present versus 110m for MySpace (but don’t state registered user numbers) – would it really double in a year given its high penetration in the key US market (85% of universities)? And yet, there’s the stat about active users doubling every six months, so it’s possible.

And what about MySpace’s likely growth, particularly when you consider one of the other statistics? Facebook’s average of 250k registrations a day versus MySpace’s 300k. Some catching up to do surely?

Brings to mind the old adage about the three types of lie: “lies, damn lies and (social networking) statistics”, as Jeremiah alludes to in a follow up post.
