Most definitely - we love honesty. Can you flesh out your comment a little? I think most businesses have problems getting traction to start out - what specific challenges are you seeing?
well, that's the problem. Getting traction is going to be very difficult with this. You're expecting people to find, or remember this site next time they need to brainstorm something. It's basically a stand-alone "feature".
Marketing is difficult, but more importantly, getting visitors to stick is going to be extremely difficult.
If, on the other hand, you do something bigger, such as create a brainstorming resource site with tips, tricks, and all sorts of useful stuff that will attract visitors - this could be a nice feature to add to that site.
I think we were also thinking of it as a platform for community thought. Imagine embedding a brainstorm widget at the end of your blog article to get ideas for a problem your company is solving.
What did you think of soneca's suggestion of essentially having a widget that lives in popular project management apps / gmail, that provides this functionality at the click of a button?
