Ask HN: Review my startup - threddie.com

"Threddie lets you brainstorm with people using a post-and-comment system everyone's familiar with. Just start a brainstorm, add a briefing and some topics, then invite people to discuss.

It's better than email, yet much more intuitive and lightweight than the mind mapping and diagram drawing alternatives."

This is aimed at small companies. I've already got a little bit of traction and, based on the feedback I got from that, am working on the next set of features (file attachments, custom subdomains, having multiple users under the same account).

This will be SaaS, with a range of plans priced according to team size and storage space.

What do you guys think?
