My honest review even though you said you're not done yet, first thing would be to smooth the edges of the logo. If you look closely you'll see what I mean.
As for the content try to minimize the article. Readers like at first to familiarize with the article, then if they are interested they will continue reading. Make sure to describe very well on the first few sentences, then add a "read more" so if the reader is interested they will continue reading. Also make good use of h1,h2,h3, bold, italic, quotes tags within the article specially on the important parts of the content, divide it into different sections to spice it up.
You get my point?
<h3>Who are we</h3>
<p>... describe who you are, <p>
<h3>What we do</h3>
<p>....what you do and why</p>
<h3>How may we help you</h3>
<p>....blah blah blah</p>
The design looks very simple but It's very adequate to the website, add some more categories even if you're still not using them. It adds a feel that the site is active, rename the uncategorized category with something else like "miscellaneous". I would recommend adding the avatars to each ready where they leave comments.
Site purpose: 6/10
My Overall rating for this website/blog is 4.6 out of a 10 point system being the best.
