I just converted to Word Press from Moveable Type and I have to say I am very impressed. The skins look way better, the install is easier, everything is laid out very well and the plugins are useful and a snap to install.
The reason I left MT was because when I moved my blog, trackback links would point to the wrong articles and it drove me mad!
Anyway, thank you for the great software! I look forward to using it for years to come.
