I started coding again thanks to codeacademy- I'm up to 500 exercises and now I'm working on other problems. Even though I'm a designer and I love what coding can do for that, I have a lot more fun solving questions I couldn't answer on my own like complicated or tedious math. Coding has helped me learn to appreciate what computers can do for us on a very fundamental level, one that's easy to lose track of when you spend so much time on the front end.
I joined here after I found so many answers to problems I was working on. This is a great community. Thanks to all of you!
