Whilst updating my myspace profile because Colin had decided that was where he wanted to hang out I found this awesome predator video
I have not really been 'doing' myspace or bebo for that matter. Preferring instead the direct interactions of Second Life and the professional links of linkedin
Also at work we have our bluepages+1 which acts as a page with all the blog and social bookmarks plus tags and ratings. Its a bit of a lepa for many people to use these, but clearly they have a place in a non centralized self organizing web 2.0+1 type of way.
