blend the background of your ads...with your own... and some half banners on your content would be great...
Try rectangular ad under first post with the same background as the whole blog. ALSO in header: Technology Blog Computer Ticks TICKS? maybe tricks?
Also you can aim on stupid computer users, for example yesterday there was a popular video on youtube, how to shut down PC quickly, press windows button then U and U for windows XP, etc.
lol btw, Why Don't use ads (for those in the post) that match the width of the post itself? also, your blog looks like 3-colloum, why not filling the right side of it? maybe something like "free software download link"? with pictures and discription that can allow people to go to the downloadable page? just anything that you think your readers want to know, - just my2cents
I suggest replacing the right ad with a square ad next to the Nokia picture. Add ad Unit 728x15 under the top main menu.
