I came to know about WordPress when I search for alternative to Blogger. I find Blogger not so customizable to my taste. First and foremost reason is Open Source of its nature. Then Categories and ability to create additional pages. These two and other nice features brought me here. Though I wanted to migrate to wordpress, the Import tool option in wordpress realized my wish in a few minutes. Just like that able to migrated to wordpress from Blogger. All my posting and comments were imported to wordpress without any hassles. Hats off to WordPress!
WordPress, you have impressed me!
