Setting up a more coherent tagging system

Hey folks... was just thinking that as the community grows we might want to add another category system to enforce a little more consistency in the tagging. This wouldn't take away the possibility for free tagging... just another drop down menu like the one we have for 'shows' right now.

 Some suggestions for possible tags

 VLEs, interviews, k12, linux, cool school tool,

 something like this... maybe a set of checkboxes... just to give a little more coordination. Then we could highlight a given tag on a given day for instance.
