Ok this is just a Rant - no thought put into it.
OSS 2007 (not sure about WSS v 3) comes with a whole heap of site columns. Now that is a good thing, but for me lately they have become a bit of a bother.
Why you might ask? Because all of the good column names are already taken.
So for example if I wanted to Create a Column called Location for one of my content types, which is a lookup and picks values from another list, I cant, because its already taken.
