What do you do as far as grammar and spell checking when you post on social media?

I proof read and correct manually. I've found programs don't detect every mistake and doing it manually keeps me more conscientious. I'm wondering what other people do though.

I don't check. It's social media. Who cares?
I proof read and manually correct mistakes the old school way.
I use programs. Screw doing it the slow way.
I don't want to answer your stupid question but I want to see the resutls.
