I'm no blogging guru, but I'm going to share a few tips that I found useful when I revamped my blog.
Burn your feeds! It allows a lot more subscription options than does a plain text RSS feed that is not very readable.
Manage your comments all in one spot. You can also rate and share comments.
3. Google Analytics
Track your visitors using Google Analytics. It shows you much more than just the number of visitors, and watching the graph change is quite exciting, even though the number of visitors per day is quite small.
4. Google Webmaster Tools
This is almost an extension of Google Analytics. It shows how healthy your website is. The healthier your blog, the more likely that it will move up the google ranking.
