One thing I'd like to emphasize is the importance of capturing email addresses from potential customers. When you launch, and later, when you add features etc, even a mailing list with a few hundred customers can make a big difference. Also, remember that getting press is just one channel; you don't need major press coverage to be successful, and even if you get press coverage it doesn't mean you will be successful. If you do get press, make sure you get as much value out of it as possible. Thousands of visitors to your landing page are worthless if they never come back; make sure to allow them to sign up for a mailing list or even preorder your product (if possible and if you already have a beta)
