Very easy to work with

Twenty Ten was the first theme I ever used with WordPress. I still use it as my preferred theme on all new projects. I’ve tried some of the newer themes, but they’re just not as clean and friendly to the user or developer.

Being more responsive would be a nice addition, as would more access to colors without having to create my own CSS. But the layout works great.

My biggest complaint with most of the themes is the ridiculous requirement for such large images for things such as the header. Now that search engines are starting to penalize non-mobile-friendly sites, it’s time to get away from 1000-pixel image widths.
