I'm not saying this is a good thing, but:

a) It doesn't really matter for most mappers.

b) It doesn't really matter for almost anyone else ;-)

c) The definitions of these tags were done in ~december 2007 probably by 
germans and the native english speakers didn't even care to correct 
these definitions till now. Since december 2007 it doesn't seemed to 
matter for most people how the actual wording is.

d) I don't think it's a good idea to change a tag description two years 
after it was documented, because the wording is "slightly" wrong for 
some parts of the english speaking world. Because doing so is an 
annoyance for anyone involved and the wording will *always* be slightly 
wrong for someone. Not to mention that a lot of people won't 
notice/ignore any changes here, as these definitions are "old enough" in 
OSM terms. My approach: Stick to the wiki definitions even if you don't 
like it and go on mapping :-)

e) Unless someone develops a nice "open power distribution map", this 
discussion is pretty much pointless and will continue or "flare up 
again" endlessly, regardless of what we'll end up with it now. So if you 
are really interested in fixing this "power wording problem", go and 
develop such a map. This will motivate the mappers much more to "do it 
right" than to conform to whatever rules set/changed in the wiki.
