There are a number of good and free blog sites where you can easily setup your blog. After setup, you should write about things that really interest you. Once your blog is adequately settled (let’s say when it begins to receive 100 visitors a day), then you should put online ads on it. You can use Google AdSense for getting ads (like I do on TechWelkin) or you can use ad service provided by other networks like Yahoo! Media.net. WordPress.com also provides its own ads.
