The more I think about it the more I want to move to Google+.
Fire away...
Mobile on Socialcast sucks (no can connect multiple accounts, notifications are terrible, chat is a separate app, snails pace development)
The future here is mobile - I really don't see Socialcast info until I login. With G+ I'd see everything.
G+ has built in hangout and chat that are always going to be better than SC or Yammer
Downside: G+ does NOT filter posts with new activity/replies to the top of the stream. They just sit wherever they've floated down too (though people get notifications of new activity).
And no dealing with salespeople from SC or Yammer (or other social networks that charge) on products that they really want to market to the fortune 100 and dealing with us (150 people) is more of an annoyance.
For $50 per year we could get evertyone a Google Apps account and share documents, etc (more likely we'd only do this with 90 Minds fellows -- ie
first.last@90minds.com). This would include Google Drive with copies of the files we all use for upgrades.
