I’ve been a happy user of Movable Type 2.66 for a long time, and along with moving my personal server elsewhere, have upgraded to Movable Type 3.35. Turns out that not just is the license constraining (I thought I was within the constraints, since I only really run a single, personal blog any more), but so is the set of available features. Implement the random pointers part of this blog — on a purely technical level — as another blog installation (as I had done back then)? Well, go for Movable Type Enterprise, or buy the appropriate additional plugin to make it all fit together.Being the “cheap” type who likes extensibility and the ability to play around with the software he uses, I’m now wondering what blogging platform I should choose to run on this Linux machine — as nice as MT 3 is in terms of UI, I won’t stick to it. WordPress? b2evolution? S9Y, as =F6 recommends? Something else that I haven’t heard of, yet?A smooth migration path from Movable Type is among the most critical criteria for the choice. A decent and simple web interface to post new items and administer comments as well. Oh, and I want to be able to syndicate an external RSS feed into this blog’s sidebar, seamlessly. (Now, that’s so 2002, as far as feature requests go…)
