I just saw it, it just looks like he did a blog about your project. I dont think he was thinking about stealing your idea. He's linking to your site in his blog. I actually like your idea, how is your traffic?
Ya, I know he was just trying to help. I just feel like crap because he got a good link from Doc Searls.
Maybe you should ask Doc searls to post a link to your site? At least, he's linking to your site. What you can do is contact him, and if he's a gentlemen he should remove it.
So you're mad at him because he's getting traffic because of your website? Usually people like to have other sites blog about them and give them more exposure.
