I've been a user of Moveable Type, but after their licensing change with 3.0, I have been casually looking for a replacement. Since WordPress seems to be so highly regarded, I decided to give it a try. Just thought I'd post my critiques, for the record:
1) What's with the Pingback?
I set up my weblog for friends and family only. I'm not interested in advertising my site to anyone (happily, I've never had to deal with a single piece of comment spam). I was distressed to learn that upon importing my Moveable Type entries, WordPress had automatically pinged back to some web site, and all of a sudden, I had robots and various strange sites pinging my site. My mistake for not going through all the options before doing the import, as I guess I should have deleted everything under the Update Services, but somehow I didn't think that WordPress would Pingback imported entries.
And why can't I turn off this option by default? I hunted the documentation and the forums, and couldn't find anything on the subject.
2) What's with the pluses and minuses for changing user levels?
Why can't I just type in a number to change the user level? If I have a level 9 user that I want to remove, it seems that I have to click the minus sign 9 times before I can get the red x that allows me to delete that user.
As well, why can't I seem to change another user's password on the User page?
3) GMT seems to be an hour behind. It's true on the http://www.opensourcecms.com page as well, so I don't think it has anything to do with my web server.
4) Why can't I delete the General category?
I tried, and WordPress says no way. If I use other category names, why does this one need to stay? I'd just rename it, but because I have already imported all my categories from Moveable Type, I don't have use for another one.
Those were my biggest complaints. I came across some bug where the last entry that was imported refused to display on the weblog (even though it would appear in the preview section just fine), but I'm sure if I had removed that one entry and re-posted it, then everything should have worked fine. I must admit, the import was nearly flawless, and that pleased me! :)
Overall, it looked like a pretty nice software. I'll keep an eye on upgrades to see if I end up trying again at some future date.
