I spent a minute trying to read the OP then gave up. I bumped into Russt's translation and "ahhhh"-ed.

Yrt ot daer siht fi uoy kniht M'i oot bmud ot daer 7331 egaugnal.

I can sympathize listed cases such as:

- Their/There/They're
- Than/then
because they are most often used in spoken scenarios where each of them bears little/no difference from another, but wh4t ish d4 p0int 0f t4lkin liek dis?

 Then maybe this will annoy you?

!|= '/0(_) {4|\| |23|) 7#!5, '/0(_)|23 0|=|=!{!411'/ !|\|54|\|3...

To, too and two are things people seem to mix up that piss me off, as well as many others listed. Sadly, even my mom gets them wrong and she's an editor. On her defense, she doesn't edit much...
