For the past 12 years, my blogs have been powered by MovableType, then OpenMelody (the open source version of MT), then back to MovableType (MTOS).
With MovableType solidly a commercial product now (at $999/license for MT6) and development on MTOS 5 down to bug and security fixes, it's time to find something else.
It's a move I've been considering for a while now. I've been wanting closer integration of the photo gallery and blog, as well as a place that could serve as an online notebook for my electronics experiments.
At the moment, I've got the usual suspects installed on my computer to play with
Most of them have a fairly sizable collection of plugins, modules and themes to work with so I should be able to get pretty close to what I'm looking for eventually. Except for Joomla, I've played with each of them a little at some point. Of the 5 so far, Wordpress is the only one I've been able to import a MovableType export file into. e107 has an import facility but I wasn't able to get the import module I wrote to work.
I think of the bunch, it will likely come down to either Drupal or Wordpress. I've still got a lot of playing around to do though before I decide on anything.
