Good site, you don't need anything else, other than improve on quality contents and for each categories, list how many posts there are for each. Probably you like to try putting the header logo at the center.
- use another attractive template - remove info links ads, because its annoying - add more site content
i see the template is good but at this stage you shouldn't place too much ads. Also it would be better than you have some posts summarized on the homepage rather only one full post.
