My first thought was, "ok, what does this do?" I then tried to figure out the site's purpose based on the limited posts but that wasn't sufficient. I then had to click to the About page. In my opinion, that's way too much thinking to just figure out the purpose of the site. Don't make a user think too much upon the very first time entering the site.

Maybe you could add a small bit of copy under the title briefly describing why the site is there. Or perhaps some catchy slogan that describes the purpose.

Exact same experience for me. Just-launched sites should have a quick, easy-to-read "what do we do" blurb or graphic.

I also echo this comment. Just one line would do it, with a link to the about page for more information.

well said, exactly the same experience here. I looked all over that first page for an idea of what it did before clicking on "About." In general, leaving a page to figure out what it does is simply not what I expect to do anymore.
