I have thought a few times about adding the ability to allow people to comment on posts here, but I always decide not to. There are two main reasons for this:

1) I realize on a subconscious level that nobody reads this site besides me and my mom (at least she says so as not to hurt my feelings), but do I really want conscious proof of my mediocrity?

2) I like being able to spew forth my uneducated biased opinions, and the last thing I want is to give people the ability to refute them.
