As you've no doubt heard, today marks the beginning of the Occupy Pittsburgh protest. Starting with a permitted march at 11 a.m. this morning, and continuing throughout the weekend, we'll be providing coverage here and through our Twitter account, @PGHCityPaper.

And as you're waiting for news of the festivities, why not take a few minutes to brush up on the underlying social and economic dynamics that are helping to drive the movement? Plenty of great charts and analysis from former Wall Street analyst (?!?) Henry Blodget here.

Be careful: Looking too closely at these charts may result in you grabbing a sleeping bag and heading for Mellon Green.
