Is anyone with Google Apps using Google Plus?

I'm probably more excited than I should be that Bristol are using Google Apps for Education. Google Mail, Google Calendar and Google Drive are going to be all very useful to use more in a work context. What I've been wondering about in the last few days though is whether there is scope to make more of Google Plus. I've had a Google Plus account for a while (plus.google.com/+StuartJohnson) but other than for sharing photos with my family (the instant upload is brilliant, if not a little unnerving) I've not made much use of it - all my networks are on Twitter, Facebook and LinkedIn; Google Plus just arrived too late for me (and was one network to many for regular use).

I like this summary of social media by Doug Ray. Clearly it's a bit tongue-in-cheek but it's pretty accurate.

So I don't under-estimate the difficulties involved in encouraging people to switch social media platforms (I haven't done). But with everyone in the institution having a Google account it seems like there's an opportunity.

So, a couple of questions:

1. Which other HEIs are using Google Apps for Education?
2. Are any using Google+ well?
