Typo Domain Names = Commission

How many of you are making money from domain names that you have purchased that are typos of other domains? (ie www.fodaddy.com)

How often do you have a conversion?

I've started playing with this idea about two weeks ago. Some have paid for them selves, some get traffic and no sales, and others do not get anything.

I have some great names (some are typos and some are .co) but I can not get approved for some of their Affiliate programs.

Any feedback about your success, failure, insight, or ideas would be great.

Wow, no one having success with misspelled domain names...
