Hi Eugene,

If you're serious about your ideas and interested in brainstorming and networking with like minded people...

My recommendation is to Focus on hanging out and participating on a variety of Crowdsourcing business idea concepts...

For those interesting in Crowdsourcing and business ideas in general...

Careful about borrowing/stealing an idea or two...

Yes... There's a few Good ones on Crowdsourcing communities...

And some interesting Investment opportunities too...

Lots of different opinions on the sharing and co-oping of ideas and Crowdsourcing...

But here's your resource directory if you happen to be interested...
