you've just created. Just as he says, after the initial attentio of big blogs like Techcrunch, the attention will slowly slow down and eventually disappear.

The web 2.0 savvy audience is overloaded with all these fancy new sites that come up everyday; and this audience will try a lot of apps, but not necessarily become a permanent user. That's why you are very vulnerable to get quickly forgotten, if you don't offer them something very useful and enduring.

I think everyone can imagine that before you start marketing your product, you need solid user activity. What investor will put money into your site if you have 300 users ? So get your product busy first - then approach blog authors. Like me. ;)
