There so much 'gimmie account' on my 43Things that I even cleaned things and 'will help' settings.
Logged in to orkut to clean out a bunch of whingemail. It certainly is faster, but, there's still not much activity in the communities. Plus it's still does not play well with others, some rss feeds or poking around without being logged in would be grand. However, gazing at the Antisocial Networks Community is worth the price of admission.
