I'm getting a bit tired of my TWiki install-- I never really liked the WikiText variant it uses, and it seems a bit heavy and slightly overkill. Admittedly, I haven't bothered to follow the project or upgrade my installation in over a year or so, but it just hasn't appealed to me.
So, I'm going to try out Kwiki. I like the WikiText, the module system, and the templating system better. Also, it seems quite a bit less lumbering to me, which is wholly subjective at this point. I haven't put much effort at all into making it fit within my site template, but that should be easy enough once I get the time.
To start off, I'm going to work on emptying out my head on dbagg3 / FeedReactor.
