After various false starts and considerable indecision, I have ended up moving from the old blogger platform, to the new one. This is supposed to sold myriad problems I had with the old platform like an inability to categorized posts (except laboriously in index posts), greater reliablity, and other cool stuff that escapes me at the moment.
I actually tried to do this a couple of times, but before, it didn't work because this blog had too many posts.
We'll see. Please comment at this post if you notice any gliches as a result of the transition.
