hey ppl i hav changed the look of my blog also i have chaged the ad placement cos many ppl on DP din like it plz check out it and leave ur comments http://adsenserockers.blogspot.com
looks good on IE but the word Wednesday does not fit in the date block, personally I think it still has to many ads but that is just because I hate ads, yoou have to make money some how, and it does blend into the site the blog archive navigation section is pretty far down the page too, i guess that is to make people scroll down the page ... cheers
The dates next to your blog posts are showing the full day of the week instead of the shorter version. You might want to fix that
The top right index block isn't very noticeable - I would make that a thin left column. I would put the ads in the second col, either as 160x600 or maybe the current size 300x250? Then the third col would be the content. I would style the ads and the content to look as similar as possible. I have found this formula works well for me on other sites. A simpler fix would be to leave the ads and content as now since you have the 3 ad blocks broken up nicely, but move the topic index to the left column and make it tall and thin with one entry per line. Easy to scan at a glance.
I suggest making sure your post format is the same throughout. Your second post has an image right in the middle with a bunch of text squeezed to the right of it. Also, the date isn't available on your 2nd post.
How can you design it? The o2 theme is designed by someone else and it was made for Wordpress...atleast give the author of the theme some credit.
You'd be better off putting top adsense unit within the post, it will blend better with the content and will increase your CTR.
