Why so little 15.ai?

I mean, I remember the first time it came out and everyone here was jumping on it. But now, with it being back out and better than ever, I’m not seeing that much use out of it. What’s the deal?

The maker consistently takes it down, sometimes for looonnng periods of time. I’m not necessarily complaining, though. They said they take it down to add more voices and optimize the older ones.

Well, it’s been up for about a week now, and has only gone out once and only for a hour.
