I used to get discouraged whenever I was learning a new framework or language and something wouldn't work. How was I ever going to learn if I kept having to go back and look stuff up?
Then after I became an "official" developer (aka being paid for it), I realized that won't ever stop happening. This is especially true if you can code in more than one language/framework/etc. Unless you have a photographic memory, you will have to "get back up to speed" many times during your career.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
