It's not just reddit..it's everywhere.  I don't know if they don't know how to spell or if they are being lazy but I blame texting.

It's obnoxious to correct other people's spelling all the time. I say this as someone with an English degree who sees these errors *everywhere*. I also see where I make them, knowing better.

If you understand what they said, good enough.
