Dreamhost Billing Screwup
Dreamhost, the host that hosts my blog and some other sites I play with, screwed up.
But they did something that most companies don't do when they screw up: They posted a very good explanation of what went wrong, how they fixed it, and how they set things up so this particular problem won't happen again.
I would prefer that the companies I deal with never have any problems, but when they do, it means a lot to me that they admit the problem, tell me what it was, and fix it.
The only thing missing is some sort of "and here's how we're going to make it right" token gesture.
(Contrast this experience with Xbox Live, which has been having intermittent problems for nearly a month, with no explanation at all from Microsoft).
