How should we handle these tags:
Should they be merged?
I've merged all three into wi-fi since it seems to be "more correct" with the hyphen.
BlueTooth is wireless, but it isn't wifi.
Depending on the use, I could see wireless-network and wireless-networking merged, but Wifi is a specific type of wireless technology.
Grammatically, "wireless-networking" refers to the concept or practice, and "wireless-network" refers to a implemented instance. But I doubt those subtleties are present...
