Typos?

Hey,
I was reading this
http://www.blackhatworld.com/blackh...870-how-make-boat-load-money-using-typos.html

But I don't like cloaking personally... I was thinking of making all those typos as tags.. but then that's too much.. it looks ugly for the user...

I was thinking of making a CSS and make display:none; but will search engines detect that? Or maybe you have better ideas?

Thanks
