Given your content, clearly separate your ads, or use text ads only. The change-background-on-hover effect is annoying. Use a white background since many logos are not transparent, and white. Remove that thin gray border, it makes the dark-background logos look messy. Your headings are not sufficiently distinct from your website titles (just remove the site titles, which will also keep the site from looking ugly when you have long titles). Put the little (3) vote counter to the left of the stars. Get rid of the dropdowns for sorting, and the buttons for pages.
When I click the logo, I expect to go to the site. I don't really care about your detailed info - that's what (more) is for. I don't want the company's often useless and spammy tagline, enforce a brief and useful description of the site. I don't want to dig around in subpages for information, and I don't want to see a screenshot of the site when I could have been looking at the site itself.
