I sometimes hit the keys next to the ones I'm aiming for, but even during IM conversations my almost-neurotic level of attention to lexical details spots and eliminates such inadvertent errors...

*For those who're still confused, if you hit the keys one space to the left of where you're trying to type, "pool" becomes "ooik".

So,
"gcw tiy wcwe nuaaws wcwet jwt vt ibw eiq>"

means

"hve you ever missed every key by one row?"

A very interesting topic, actually, but it's doomed to spamdom because people'll start posting any old nonsense in "missed by one row"-speak rather than staying on-topic.
