Today’s challenge: find out how Bolder wants you to make your community a better place.

The idea is sort of like GroupOn mixed with, uh…well, I’m not quite sure. Every few days, a new challenge will appear, sponsored by a local business. If you do the challenge, you can claim a reward. Today’s challenge is to buy local, and if you do that, you can get a free chocolate from Charles Chocolates, an artisan chocolate shop in San Francisco. (Obviously, the “local” part of this equation may have to wait until they expand to more cities.)

So, what’s interesting about it? Well, the idea is that the challenges help build up your community. Local businesses challenge local people to do something interesting, and then people talk about it. You might get to know your neighbours online, or learn about new businesses you haven’t heard of before. It’s a pretty neat idea.

At this point, the only thing holding these guys back is getting enough local communities engaged to draw an audience. If you’re interested, let them know. Follow them at @actbolder, and check out their blog.
