Golem is developing an API that will let anyone create custom tasks, and the whole point of their reputation system -- which is the main criticism of Golem on the XEL website -- is to facilitate custom work that couldn't be verified by a central authority (whereas general computing tasks like rendering could be easily verified).
I thought the whole point of XEL was to let people do custom work, but it sounds like Golem is already doing that?

That doesn't explain anything and it completely mischaracterizes the Golem project: https://blog.golemproject.net/the-challenges-ahead-933f040cba95
1. Golem is decentralized
2. Golem results are verified
3. Golem is not limited to general tasks (like Blender)
If that's the best explanation you've got, I'm even more convinced that XEL is a scam / vaporware.
