”dont overanalyze" you say,
"you really can't fight this stuff."

Yes, but

it really slows down my reading. I don't know how to skate over it.
On Facebook I'm getting so used to having to decide between there\their\they're ; your\you're ; to\too\two that when I read a perfectly well written piece I even find myself stopping to check - did they really mean 'their' or is there a different meaning to the sentence if they meant 'there' ?

I never(not for the last fifty years) used to think about it but now I even find myself writing a 'their', then stopping to check that I really did mean 'their'.
