webdev has been made into a synonym for webdav. This is a mistake (No offence, Bart.) Webdev is surely short for "Web Development" - however I can't prove this because it's now impossible to find the item that's tagged with it. (suggestions?)
Anyway - webdev probably isn't a great tag for trex. Sure - it's all about web-development, but questions that really are about that are probably off-topic.
Wouldn't a simple deletion or re-tag have been a better solution?
