I have setup a Google Plus page for MyPivots:
https://plus.google.com/b/116175848514631524771/
if you use Google Plus you may find this convenient to keep up-to-date on the important posts that I'll try and post there.
All of those posts should be duplicated on the Twitter and Facebook pages for MyPivots. Feel free to follow, join, like all or some of them, whatever is most convenient and productive for you.
