Why I waited so long to switch.

I held back from switching to Movable Type for a long time after realizing that Radio was no longer the ideal weblogging solution for me. Radio's news aggregator changed my life. When I finally gave up dealing with Radio's memory-eating I couldn't justify moving over to Movable Type because of its "lack" of aggregator. Eventually, I wised-up and realized that a weblogging tool and news aggregator are two different beasts. I'm now using SharpReader. I recommend it to anyone.
