Chicago's bike-sharing program has hit the streets. Are you in?

Divvy, the city’s new bike sharing program, launched on June 28. The initial reviews are in. Here's a handful of verdicts:

• The bikes, even if they're a bit bulky, are functional.
• The program itself has problems, but that's pretty typical.
• This is not the kind of bike you'd take out for a ride with Team Judson. 

Yet the biggest questions about bike-sharing in this city will be answered by the commuters of Chicago.

Will you actually sign up? What kind of plan will you choose? If you're already on board, where have you been riding?
