The AppStore launched, meaning Jott for iPhone is now officially live. My company has been working really hard on this, it's great seeing it out in the wild.
I remember the Mac shareware boom in the 90's. You'd get a CD-ROM tucked inside a Mac magazine stuffed full of shareware goodies and the quality was actually pretty good. I'd usually find a few gems per disc.
I remember the version tracker boom several years ago. It was sort of like the first boom but with all the improvements the Internet enables, like ratings, comments, and "more like this" sidebars.
I think the AppStore boom is going to be a much bigger deal. The distribution is better, sure,, but the exciting part is that this will be a whole new platform.
I think I'm about to download about 100 new apps in the near future. I'm not kidding or exaggerating.
