"Blog" is an abbreviated version of "weblog," which is a term used to describe websites that maintain an ongoing chronicle of information. A blog features an online journal or informational website displaying information in the reverse chronological order, with latest posts appearing first.

How to start a blog?
1. Free Blog Setup: Here you will get a sub domain blog from the main blogging website. For example if I am creating a free blog in wordpress.com then I will have to create reddyash.wordpress.com. reddyash is the blog which is created free. The word FREE always comes with many restrictions, you will not have all features activated in a free account. You cannot sell ads in free blogs. I think in Blogger you can integrate google adsense code and make money with ads.

2. Paid Blog Setup: You can create a blog using your own preferred domain name, all features activated and you can have your own blog email (info@blogname.com) to look more professional. If you are looking to earn money then paid version will be more effective.
