Blog, blog, blog,blog, blog--I am getting sick of this word!
None the less, a very big newspaper has an article about how readers can make $$ from their you know whats.
Highlights--

• Google Adsense
• BlogAds
• Affiliate sales like Linkshare and Amazon
• Schwag a la cafepress
• Tip jar/ donations

(Of course, if you really get into blogging, you will probably end up trying to make money as a blog consultant, author of a book, or paid shill, (okay, hopefully not the last one.)
