Google+ is finally available for Apps users.
Not sure how or whether this will cause Google+ to kick off again, but at least I can have access to it on my standard email address (which I pay for).
Currently posts have to start here to flow out to the blog and then to Facebook. I hope this won't last long!
Also: the automatic invitation to Google+ when you put someone in a circle is a bit cheeky. Sorry if you've been bombarded.
