I started out as many not-so-smart or very-smart people do with HTML & CSS. That was back in 2005 or so, which made me 13 years old. As of 2011 I am quite comfortable with PHP, JavaScript (and it's libraries). I've done some very small experiments with Python, Ruby on Rails & C++. That all being said, I have a crap ton to learn and I am nowhere near a professional level.
