Umm, a few thousand users is basically 0 on the web. Investors ignore you until you have half a million.

Are you one of the founders?

So that's what business is for you? Are you making a product for yourself or for investors? Why should I care what investors care about - I'm trying to make a product for users, and not for investors. A few thousand people following my product is EXCELLENT, because out here in RL, a thousand people are not following me.

You have the wrong attitude if you are only focused on what investors want.

You extrapolated that comment way too far.

They have thousands of users?!

Unbelievable if true.

Check your Compete toolbar when you visit their site. Plus it is a steady traffic which tells you that every single morning someone is woken up by the social alarm clock.

EDIT: To answer your other question, I am not a co-founder, but looking at pure numbers they are doing better than my last two trials and those of a lot of us.
