If you're like me, you may already have a blog, but if you've been wondering about getting one up and running, here are some open source blog engines. There are tons of open source engines but here are just a handful. If you have other great engines, please post them in the comments.
- DasBlog - Originally based off of the BlogX engine, Scott Hanselman and many others help contribute to this engine. It uses XML files to store everything so it helps aid in migration and ease of updating.
- SubText - This engine is powerful and flexible. It is written in c# and uses SQL Server for the data source. This engine was modified slightly and now runs the MySpace China's blog engine!
- BlogEngine.Net - This engine can actually use either a SQL Server or an XML file for their data source. This is constantly one of the top downloaded items on CodePlex.
- Wordpress - This is a PHP / MySQL based solution with a very active community and user base.
All these engines are extremely easy to get up and running and can be modified to suit your needs. Also they are a great way to see how other people code and solve problems. I personally learned a lot when I modified SubText for my personal blog. If you want to try out a new blogging software without losing your current data, I suggest trying BlogML for making the data conversion to a fairly painless process.
