The tagline is "watch people code products, live". The word "products" appears in almost every piece of copy on the front page. Why not just "watch people code, live"? Why the focus on products? What about open source code, personal projects or other things that will never be sold?

Classifying streams by programming language is also kind of odd. Lots of projects use multiple programming languages. A better classification might be what general kind of code is being written (machine learning, graphics, UI, web frontend/backend, games, etc).

That said, I'm very interested in this and hope to see it succeed!
