I have a relatively new job with a marketing start-up. I develop the websites they sell.
I love Wordpress, I an I have been using it here for.. well, ever. When it came time to consider producing websites quickly, guess what I chose?
I have a formal education, but nothing, and I mean nothing, in the world of programming, online or off, beats doing. I have experience with php, so hacking on Wordpress was not that big a deal. The only real hurdle was that I really only ever have hacked on themes I have used. Basically The Codex and I are getting really cozy.
My whole point is this; keep mucking around with things, even if you think you know enough.
