Lots of useful and interesting information but don't you think you might lose some of your credibility on account of over using ad sense? Some people might think the purpose of your blog is to make money from adsense rather than to tell them how to do it.
Good blog. Put some title on the header so that it gives user a quick overview what's the site is about..
nice blog, informative, just make sure that ads did't disturb the reading the content. All the best..
