I've been wondering about this too.
rofl. Last week, I googled "most popular celebrity", autoclicked the first result, and picked the first chick on the page. I scampered off to register a common misspelling of her name, figuring I could blog it to smithereens and suck profits happily ever after.
I then
1.) Realized how much I don't give a damn about celebrities, and
2.) Educated myself on typosquatting.
>_< Newbman!
