I am not a huge fan of sliders until they are used in a decent way. The only way I sort of like them is in an image gallery but even then it has to be somewhat incorporated with a lightbox, colorbox, whatever you would like to call it. These sliders are slowly becoming a bit more popular with theme developers because it can solve a few issues for the user. The biggest drawback is that they will no longer have that slider when they ultimately redesign the site and switch themes.
Conducting WordPress theme reviews can be a great way to contribute. Some people love it, some hate it, and others tend to watch from the sidelines. This is a glimpse of what three years and over two thousand theme reviews may look like for those that also want to contribute.
