I'd say launch as soon as you can. Post your product here, digg, etc., and try to get it blogged, and hopefully TechCrunched. Watch Mike Arrington's video at startup school on tips to get your site blogged. Have someone leak a twitter message to Mike about your startup. Good marketing can be done effectively without any money. With competition on the horizon, launching something less than perfect might be in your best interest, because you'll not only get the first jab at the market, you'll have the ability to iterate based on user feedback so that your product will be more tuned towards users' actual needs by the time your competitors start trying to gain momentum. Differentiation will come as you begin to mold to your users. It's a matter of agility.
