Back in Jan I went to a person well respected in the startup community (PG knows her) in BOS. She was a friend of a friend, I've known her for years..she previously had a high profile startup that crashed in the dotcom era. I wanted to bounce the idea off her and get her feedback. So I sent a presentation (marked confidential) and followed up with an hour long chat, which was helpful. She moved to the west coast the day after we talked and 2 weeks later I find that she taken my 90% of my idea, mixed it up with social network and gotten seed funding from a small west coast VC. I've been developing this idea on a shoestring and on the side for 6 months. I've got a lot invested in this. She's hired a indian development firm and been spamming blogs with her site name to get registrations. I've applied for a patent, but not sure it can be of any help right now. What action should I be taking? (besides wanting to run her over)
