I think "blogsome" is different blogging website, and "wordpress.com" is different. I don't understand why you are mixing up "blogsome" and "wordpress" here.
Anyway, I just recently created a blog with "blogsome.com" with the aim to earn money from google adsense, but I found that there were already google ads from blogsome itself. So I stopped using blogsome, and I think now I should stick with "wordpress.com" to create blogs. I hope here I can apply for Google adsense.
