I have a very basic wordpress blog at http://tipstoquitsmoking.wordpress.com what can i add to jazz it up a bit?
Changing the theme and adding a nice logo for sure. Images could be added to every post. Description/keywords meta tags could be added to improve onsite SEO. Good Luck!
Some great articles and lots of content. Well done. As Blichev has mentioned, you should create a nice header for the blog and possibly select a completely different template. Best of luck with it.
