In case you didn't notice, Google+ is now open to everyone. You no longer need an invitation to join. Just go to www.google.com/+ and start your account, then add Thom Hogan to a circle (of people you want to follow) that you create.
If you're a fan of my teaching points (image plus commentary at the top of the page), you should probably join Google+ and follow me. Most of the images I've posted so far have fairly long and interesting discussions. Please don't use those discussion threads to go off-topic or ask unrelated questions of me, though. One nice thing about how it's worked so far is that the discussions are actually just that, and I'd like to keep it that way.
