Google was kind enough to send SAI some invitations for its new
social networking service Google+, and after a few hiccups we've
been able to get on the service.  First impression: it's
Facebook. With video chat. Only it doesn't have any people on it
yet, so it's not as useful.  There are some subtle differences
in how you invite friends and so on, but the MAIN page -- the
page that shows up when you click your +name (I'm "+Matt") in
the black Google toolbar at the top of Google's search page, and
that serves as headquarters for all your Google+ activities --
looks almost EXACTLY like Facebook.  There's a status bar up
top, icons for adding photos, links, and videos, even a spot in
the right hand margin where they suggest other people you might
know.  It's like they cloned it.  See for yourself:  Google+
