I have always found Twitter to be very useful, getting a lot of great links and news items from people I follow. That said yesterday I never visited Twitter until late in the evening. I was using G+ yesterday instead.

I find little value in Facebook but family members and some friends really use it a lot.

I hope that Twitter, Google+, and Facebook all do well because they serve different people's needs (or wants) and all three are platforms for developers, basically the ocean a lot of us live in.
