Great to see zds in here actively addressing comments. I was really surprised to find the site redesigned after not having picked it up in about a week (been to busy to walk through the rest of my missing tutorials).
I have to agree with the sentiment currently, the redesign throws way too much in your face all at once and I can only imagine for a beginner that you would easily be pushed away from the site if it was your first time trying to get into it.
For me, I would like to be asked up front which path I would like to take: Are you looking at applications or are you looking at web apps? After that only show me the lessons that relate to that path and pull back the rest of the site design to be as minimalist as possible.
What would also be great is if I didn't have to bring up another tab just to look at the QA section when I get stuck trying to implement a solution.
Finally, would love if the code panels were actually a bit bigger so that when you have a multi-line program you could view all of it at once. I don't know what is the most used resolution when viewing the site but I imagine you do have room to make the console bigger regardless.
Love the product and I am definitely going to keep using it regardless of the design.
