Just getting into blogging? Here are some resources that can help:

Amazon Honor System. Get donations to pay for your site.
Amazon Associates. Earn referral cash. I have a search bar (mostly for my own use), and will link to books, games, and DVDs that I review or recommend.
Paypal donations.
Stat counter. I put a block of javascript on each page to count hits.
Google Adsense. Personally, I hated having ads on my blog so Adsense didn't last long here. But some people are making some money from it.
Blogads. I hear Blogads also are a money maker.
MyBlogLog. Track where people click on your blog with javascript.
Feedburner. Allows you to track visitors, also allows you to improve your RSS feed.
Bloglines. An online RSS feed aggregator. Basically, you can publish an xml feed (Blogger does so automatically) and people using Bloglines can automatically see when you create a new post. You can also set up a profile and username to automatically list your blogroll (as you can see to the right). I do all my blog reading from Bloglines these days. Much easier than clicking around searching for new posts from my favorite sites.
