Q:

What should be done with the 'edge' tag?

There has been a discussion about it on the comments of this answer but that is another question.
I think that this tag (edge) is used for several case, such as mentioning a computer model, network service, or Ubuntu Edge. But it is not specified in the tag summary at all.
I'm a bit tired of review edits adding and removing this tag and I don't know what to do.
Should we create a synonym to ubuntu-edge or delete this tag? Another suggestion?

A:

Please do not allow this tag to live!
There are too many things that use "edge" in it's name, and the system isn't smart enough to know if it will be really useful. Examples:

Ubuntu-edge, the operative system.
Edge of the monitor/tablet/screen/etc.
Thinkpad edge, 
Edge swapping, a effect of compiz
EDGE (Enhanced Data Rates for GSM Evolution) the digital mobile technology
Edge, of a window.
Others "edge"s of anything...

Because of this, this tag should be avoided/nuked.
If tags are needed to contain "edge" they should use the hyphen (-), example:

thinkpad-edge (I really do not make too much sense of this one... someone might)
egprs and in the excerpt/wiki say that is also know as EDGE
no other case scenario where "edge" could be useful for looking at question/answer, and won't give headaches later.
