I like Google plus. The clean interface, the way photos and albums are displayed.
I love the fact that everything is but a few keystrokes away, in any browser on any computer.
My big tip is to use Chrome. I have it set up so that, when it opens, my profile and pages are set up to open in prefs, on separate tabs and importantly in their own identities.
This makes it really easy to maintain and if I get confused about my identity, which is pretty easy, I just quit and restart Chrome.
Here is a set of links to my profile and all of my pages, do come and say Hi!
