My first impression is that it's a decent site design but there is too much information.
First, I suggest you omit the "users online" and "guests online" stats, as they are going to be low until the site gets a little bit popular. For awhile, it'll appear to be a ghost town and actually repel people from using it. It's a great feature, though! Just put it on the backburner and release it when the time is right. (Or, you can extend the meaning of "online" to mean a longer time span so that the number are higher)
The font is too squished together and it impedes readability. I suggest each topic have more height to it, and more space. Definitely needs some padding in the description and the font-width (or whatever it's called) needs to be higher.
The sorting options appear to be broken, and there's no way to get back to the original view besides hitting the logo button. Make "what's new" a link to the page.
When clicking into a post, I'm confused as to what it is is supposed to be going on. I clicked on some democracy thing, and it showed the same truncated comment, and then 4 comments below. What caught my eye was a big box saying that I can't "collabrr" (which I don't even know what that entails), and a thing on the right flashing "no host".
Very confusing as to what the site does in general. "Our long-term goal is to create a unique site in which users can interact in a variety of ways to seek information, present information, or just interact in a community of unique individuals." It might hurt to hear this, but that sentence is essentially meaningless to somebody who knows nothing about the site. You could describe any number of websites that way.
Hope that helped.
