Press releases are best used when you have something ready for the masses to use. If what you have is ready for its beta then I would go ahead and get journalists involved, but if it's not ready for the average user, then I would hold off. Of course if you can use the press to build public anticipation then it would be worth it. Just be careful not to let anything break.
