Commas and periods are interchangeable to me anyway.
Maybe it's because I read so much? Dunno.
Are you being serious? You 'read so much,' yet you don't care about punctuation? That's basically a paradox. If you read a lot, you should give a rat's ass about when something is capitalized or not, and whether or not the sentence has at least somewhat correct punctuation. Especially the fact that commas and periods indicate
two totally different things.
