I used to be a grammar nazi, but now I accept that we are witnessing hyper-evolution of written language. Before the internet, I didn't realize how pervasively people confused its/it's and lose/loose. (I knew there/their/they're was a common problem.)
I previously assumed languages typically evolved through "erosion" by dropping letters or spaces as a matter of saving time or space. But in today's computerized world, time and space are cheaper, so grammar exceptions seem to what is eroding: its/it's is an apparent punctuation exception and lose/loose is a pronunciation exception.
