I don't like this current tired of promoting a start-up when there is just a landing page, Its just not interesting. We know nothing about what they are doing.<p>I would never enter my email address into a "LaunchRock" powder landing page, it could easily just be someone collecting email addresses for another purpose. I think there is also a trend of people putting up these "landing pages" with absolutely no intention of making anything unless they get some interest.<p>If you are starting something interesting, show us what you are building! If you aren't ready don't promote it!
