AFTER Facebook's announcements about their new system, style and upgrades (and floating the company..) over the last couple of weeks, I expect that Google will be revisiting their so-far-pretty-lame "social site" attempt (I don't know anybody using the Google social site, either..).
Especially now that Facebook will be targeting more advertising revenue, and will be threatening other internet businesses like Google (probably the biggest advertising company in the world at present..), and maybe also other internet players like Amazon and eBay ~ after all, after their float, Facebook will have to look at growing their income base..
That's why I say that I don't consider Google a proper "social site", as yet
~ maybe they should buy "MySpace", and use its previously-successful model to improve their own struggling would-be social site efforts. Plus, with Google now owning YouTube as well..
Then Google could be a "real"
member of that "social site" set...
