Lots of people have pointed this out. I was aware of this when I wrote it, however the entire point of the site is to stress basic grammar to the kind of people who would never use either in its alternative context. Most commonly (i.e., almost always) effect is a noun and affect is a verb. I'm certainly taking this under advisement, but I'll probably just add a clarification along the lines of "Effect is almost always a noun; affect is almost always a verb."
