I’ve recently spun off the PHP part of my portfolio site into PHP Developer (alas, I couldn’t get the .co.uk). It still needs fleshing out a bit in terms of content, and I’m not really promoting it due to my full time job, but already I’ve received a few enquiries through it as a result of the keywords in the domain name.
Unfortunately I’m not the world’s best designer, so the site is still using the default WordPress theme, but I’m hoping to get a custom theme designed for my three freelance sites sometime in 2011.
