Why do so many questioners say "loose" when they mean lose?

Because they don't know what they are talking about =D.

Because they cant spel, duh.

I was helping my friend unpack for college, and there was a bulletin up that read something along the lines of, "How to loose a grade in ten weeks." Upset by the fact that this was a university and that that person couldn't read, I actually took the liberty of ripping one of the O's down. It now correctly reads, "How to lo se a grade in ten weeks"

Just poor english. A sign of the poor educational standards of the time.

omg that annoys the crap outta me. It's because they obviously don't know how to spell. Same with when someone when spells "loser" like "looser" lmao

they are simply uneducated.you do see that alot.
