I really like Forrst. It's got a good mix of code and design for a generalist like me. I think I get something out of it. Perhaps that speaks to my level of competency but I find it useful since I am a jack of all trades. If I have a really hard coding problem, StackOverflow is going to be where I go. For a stream of new stuff or latest techniques I may not be aware of, Forrst is for me.

Also I think Kyle has done a great job as developer/designer. I was impressed. If someone doesn't like it, they are welcome to create a better version.

As for the monetization, I have to agree w/ steveklabnik that designer/developers are a hard bunch to squeeze money out of since they aren't used to paying for these sort of services. I could be wrong.
