Google+ for geologists

I am not certain if this is a good idea or not, but when a friend sent me a Google+ invite to my personal email address, I used that address to send an invite to the address attached to this blog. After all, this is the address that I keep logged in and have my GoogleReader geology feeds set up. Unlike the account associated with my personal email address, which had no suggestions of people I may know, this address came with a bunch of suggestions, several of whom I recognize as fellow geobloggers. Therefore I created a circle called "geologists" and added them to it. I have no idea if it tells you that you are now in my circle, but if it does you now know why…

It let me set up "sparks" for "metamorphic petrology" and "orogenesis", but they don't look like they have much information available at this time.
