i can see your site actually waste so much spaces especially the side bars. try using the three column blogger template. and put more ads to it not just adsense. I've been wondering what other tweak should i do for my blogspot too. if any of you guys know please reply to this thread.
a more refreshing design is required , try searching for some free blogger templates and do some advertising like ask some of your friends to but a link to your site from there blog post more articles
