During the course of the last 6-12 months (approx.) online I've seen more and more the mistake of using "it's" in place of "its" and the other way around.
While my habits might have slightly changed, I'm talking about a huge difference here: a few years ago I knew it was supposed to be a "standard mistake", now I notice it almost daily! Even by native speakers!
Assuming it's not "just me", did you notice that? Have any idea of what could be the cause? The only logical thing that comes to my mind is that the Internet is now more cheaper and worldwide, so (no offence intended) we have more non-native speakers and more uneducated people. With "uneducated" I do not only mean they might not know proper grammar: I mean they might not care to write correctly.
