WordPress is one of the most popular blogging systems. My only experience is at a contract job for about 5 months. I used it as my internal blog. I convinced someone to install it for me but it didnt’ catch on with the rest of the company. My personal website hosting service offered it and I tried turning it on but ran into a snag. In general, I liked the features with support for multiple categories and pages off the home page.
Not sure what I’ll be posting here but I wanted to check it out. It would be nice to be able to recommend it to friends and perhaps use it to create home pages for various organizations which I’m currently using Manila for.
