Like joshstrange I want to love this but it's hard. I echo the comments about the front page. It's a lot of marketing speak, but I could really use a 25 word version on what this is going to do for me and how I'm going to use it.

If I go to the examples, I get the chance to see a ton of example programs. But I'm dumped into an IDE that I've never used. One change would be to put a run button as a top menu choice. It would be really helpful if the programs had a comment at the top about what the program will do.

I also looked in the FAQ pages hoping for a "how does this work" "how do I use this" etc. and also just got two questions about "how do I pay for this".

Josh got downvoted pretty hard, (and I guess I'll follow), but he had some spot on comments.
