set up a private beta email invitewall for your site with a basic paragraph explaining what your site does, spam this everywhere you can and collect as many emails as you can. set up a subdomain to redirect to your site and post it here. kill said subdomain after 3-5 days and tweak based on feedback. in the mean time pitch to techcrunch (mashable is worthless in terms of coverage) through their email system, twitter links, and their forum. if it's interesting they will pick it up, though michael arrington probably won't be the one writing it up. just go ahead and launch. email everyone on your mailing list. send the links to everyone you know. browse through blogs and whenever something related to your product is mentioned make a mention of it in the comments. techcrunch doesn't make or break you.
