I'd really like to know if the apostrophe-s thing on plurals is deliberate. Like "teh" and "I can has" and the like? The number of people who do it suggest that it is deliberate, and if so, fine.

In case you don't know what I mean: post's where word's meant to be plural are getting 's slapped on the end's. It's never grammatically correct unless it's a possessive or contraction. This is what tells me it's deliberate.

I get the joke of "teh" and "I can has." They're funny. I may be too old to "get" the apostrophe-s joke and I guess that's fine too. Out with the old. It's cool. I'll not be the guy who is just a little too old to be at the club, like that Chris Rock joke goes.

I'd just like to know. Apostrophe-s on plurals: Deliberate or Ignorance?
