Web developer and front-end designer. I used Wordpress as my main CMS for a number of reasons. 1. It has a wonderful community and there's a plug in or a solution to almost anything 2. despite the team's best efforts to keep it exclusively for blogs, it's a brilliant website CMS as well as one for blogs 3. the admin screen is incredibly simple for the less technically able and 4. I'm too rooted (read scared) to migrate all that knowledge to a different framework.
All I have to do now is decide whether it's better to build my themes from scratch or bastardise some other, whether it's the Wordpress Twenty- series or some of the bare themes, current favourite; Starkers or Big Blank, just evaluating _s.
