Is that with MySQL? I've used it for scores of projects, always with Postgres, and it's never failed me, even if it's been a bit slow when there are lots of rows in play (which isn't really South's fault)

Yeah, with MySQL. You've probably got a pretty good point there. If I were to start a site myself one of the first things I'd do is never use MySQL, though it does improve ever so slowly.

In the latest version(beta?) you can actually have a column with 'default current_timestamp' and a column with 'on update current_timestamp' in the same table after years of only being able to have 1 column per table auto that way.

I don't remember the details, but I think I had to fill a column with zeros all the way down just to drop the whole column in the migration anyway or something along those lines.
