In a world driven by commercialism, there are few who can resist the temptation offered by something like Adsense. Adsense generates income for the owner of the site each time an ad link is clicked by a visitor. The more traffic a site has, the better the chances of generating greater income. The better the content, the greater the chances a site will have more traffic.
For Adsense to make sense, you would have to calculate whether the time you input into your site is worth the income generated by the ads placed on your site. This is difficult to do if you are just starting out a blog. Not much to say, not many visitors. It takes time for word of mouth to spread about how incredible your site is. But if you don't get any visitors within a year, you are pretty much an unqualified blogger. Websites are in a popularity contest where the most visited get to rank highest on the list, which brings more visitors, which get your ads clicked more often, etc., at which time Adsense will make much more sense than now when the only person willing to click on your ads is yourself, which, by the way, is against the rules.
