This is Your Brain on Twitter (vs. Facebook)

The science of social media is starting to attract attention.

At least one scientist is investigating the effects on working memory of using Facebook vs. Twitter.

His conclusion (oversimplified) is: Facebook makes you smarter. Twitter makes you dumber.

More specifically, Twitter requires less mental processing and fewer synapses firing. And reduces attention span ... as if people these days didn't already suffer enough from this problem.
