Thanks for sharing :) I find Google+ to be useful for sharing photos with people who are not on Facebook, because it still allows you to share with an email address and it works pretty well. Not sure how to do this in FB, but I bet there is a way.

Also, Hangouts is probably the biggest unique thing for Google+. By far the best web-based, free, multi-person video chatting experience IMHO. Not to mention it can be tremendously productive if need be, with in-window document editing and screensharing. It's somewhat based on the video conferencing solution that Google has been using internally for remoting into meetings for a long time.
