ermm, ok..
1. less posts on the front page
2. lighten up the grey in some areas.. it tends to just be a big grey blur to me atleast
3. increase the line height on your text, that will improve readability tons.
4. fluff:
a. the tags are useless the way youve used them (unwieghted). if it were me, i would kill em or change the way they’re displayed.
b. the “site policies” — how bout another page for that? with a link in the footer??
c. you have a categories section AND a feed section. Those are combinable using get_cats or list_cats, something like that. I do it on my site, so I know its do-able.
d. the stats in the header — no-one cares, and i say that ONLY because you have so much else going on. Ask me, and that needs to go all-together, or be placed signifigantly lower on the page, like the footer.
e. same with the “powered by wordpress” in the header” It ought to be lower on the page.
Your site looks like a reallllly busy phpNUKE portal, not a blog, and its quite unreadable. I really dont mean to be harsh, but I cant help it.

A rule of thumb: Follow the above the fold rule. the most important stuff, if possible, needs to go there. Everything else takes away.
