I joined Pinterest in 2010 but have never used it that much ... as it is it's hard to keep up with Google Reader and blogging and Facebook and Good Reads and lord knows what else is out there. Hoping to Pin more regularly though since it is a great way to keep track of things. The board I've used the most is Recipes to Try - seems I've got to get cooking. Another motivating factor to get more involved is that founder Ben Slibermann seems to have rocked the Alt Design Summit when he served as keynote speaker last week. Super cool!
Here's to productive pinning in 2012 (note Pinterest link to the right).
