I quite like it. I'll get to porting it to Ruby.
If anyone has a better idea on how to keep the logic in one language, but make it accessible to everyone (preferably without inventing a whole DSL, that would end up being just like a real programming language, but worse), please speak up!
Seems strange to me. Seems like for a lot of this, where it's often HTTP based anyway, you could implement much of it in C without it being a complete nightmare.
Honestly, I don't know what "deliver integration over the Internet in a web app" means in this context at all.
I'm sure there are already C libraries to make REST calls easy and the rest is just creating the proper queries and parsing responses into usable structures, etc.
Like I said, the things you're saying are either vague to the point of misleading or you're extremely confused about some very basic things...
I'm a huge fan of "web techonologies". Seeing as Go is a great way of writing web services that back web apps, it's a pretty good fit. There are thousands of things that aren't possible, and never will be with "web technologies". Every web technology is hitting some web service somewhere that's powered by code that does not run in a web browser.
"Solving the Cloud API problem" sounds like... well it's sounds like a bunch of jargon speak.
