So, the catalyst developer blogs didn't really work out well... It's been a pretty quiet place, to put it nicely. That's why we've decided to replace them with a Plagger based planet aggregator. It'll be up at planet.catalystframework.org sometime soon.
As for myself, I've found I need to write on varied subjects, so the confines of random got a little narrow for me. Instead, I've set up a livejournal account instead. To get only relevant stuff, you can check out the Catalyst tag.
Note: Anyone know if livejournal lets you get rss feeds from tags? Haven't found any info on it yet.
