Setapp, the Netflix for Mac Apps service, got a nice update yesterday improving on App discovery with better App summaries and categories of apps. The overall user interface is much nicer now. Both prettier and more accessible.
I first signed up just to try it out but I'm finding Setapp pretty useful and I'm still using it. For $9.99 per month you get access to 73 apps from 65 vendors, worth a total of $2,387.22.
I have talked to a few developer friends about this business model and everybody is curious. Right now, it's very tough to make a living in the software business. If something like this takes off, it could be quite lucrative for developers. While it's not the only answer going in the future, it certainly could become one of several revenue streams for successful software developers.
Anyway, if you like to tinker with quality Mac apps I recommend giving it a free month trial and seeing if it fits for you.
