Almost every answer on the site could use editing to mark the words being used as examples. I don't really feel comfortable editing a bunch of posts just for this reason; plus, I feel like I can't keep up.

Formally, if should be used when you have a conditional sentence and whether should be used when you are showing that two alternatives are possible.
which is hard to parse, we should encourage something like
Formally, if should be used when you have a conditional sentence and whether should be used when you are showing that two alternatives are possible.
