If you click on this link you'll find a chart that shows different health conditions and sufferers' participation of vs. benefit in online social networks.

I knew I was doing this blog for a reason!
P.S. - Couldn't think of another word for "sufferers" - but I'm fully aware that I overuse this word. I'm not in a constant state of suffering, and I hope you're not either! :)
