I switched from MT to WP about a month ago, before the recent licensing issue.
I ended up going with WordPress because:
- No rebuilds
- The community and the developers. When something seems to be wrong or a bug is found, they fix it right away. Also, I was very impressed with the fact that they did communicate and did come here to help the rest of us out. :)
- The Typekey issue (I moved from Blogger because of having to depend on another server or service to post and when they were down or my comments server was down, nobody could use it. And I was not all that keen on having people have to register with a service they might not want to register with to leave a comment on my blog. Also, at the time, the rumor was that the Blacklist was going to be obsolete and there would not be a new one, but that rumor has been dispelled after I made the switch. I think the solutions that WP has for comment spam are pretty good and much simpler than having to use Typekey.)
- My wanting to get a sense of PHP and wanting to learn more about it.
- Just the fact that this program is so simple, but yet it does everything I want it to do.
- Server space. My old MT blog took up a lot of space on my server. MT grew to become more complicated than it really had to be, IMHO.
When I was looking into WP, the only disadvantage I found was not having multiple blogs on the same install. But there were so many advantages, that I decided that not having multiple blogs on the same install was something that I could live with.
I have been nothing but happy since I switched over. My husband took a look at WordPress after I got it up and running and was so impressed with it, he made the switch, too.
