A la Facebook groups I guess, Google+ now has pages should anyone here feel the need to add another avenue of alert, if alert is the right word.
As yet, if nobody here is on Google+, it's not exactly as obvious as Facebook is in terms of 'oh here look, there's a Mayan Calendar group' or whatever, but there is a search box and, being Google, it works darned well - to my bemusement, one Patrick Geryl is on Google+. Only one post so far but there we go. And only 4 friends so far. But the search box works, thats the point.
While I happen to believe we don't need to bother (I'd like to think Google+ members are more intelligent than Facebookers, but then that's mostly because it doesn't have 800 million members yet), it might be one to look out for. Or ignore. I simply don't know yet.
