On documentation
If you're going to write documentation, then make sure it means something. So that if I find some term in your UI that I don't understand, and I decide to look up the term in the documentation, I get something more than just the fact that the term exists and that I can switch the feature, whatever it does, on or off.
Because that doesn't help me squat, thank you very much.
I can't count the times I've looked at documentation to find out what the 'Foofrobber' does, only to find:
"Foofrobber: Enable this to frob your foo."
Sometimes even:
"Foofrobber: The barmatic 2000 (tm) includes advanced, state of the art foo frobbing facilities. Enable this feature if your barmatic 2000 (tm) needs to frob your foo."
