Online marketplaces are some of the greatest insights we can get into the contemporary human condition. The amount of sociological studies that could be conducted on Craigslist is no joke. There's something about offering or seeking goods and services that brings out something revealing in even the most reserved of people, including their willingness (or ability) to avoid typos.
It's true, most of us slip up on the keyboard now and then. However, you might think that when it comes to the important business of making money, people would take a little more care. Apparently this isn't always the case, as @cooperownbey pointed out on Twitter. Revealing how it was possible to find some real secondhand bargains by intentionally misspelling the words you are searching, numerous others came up with some equally hilarious examples. As nothing seems to be getting any cheaper, it's probably worth taking this advice. It's practical as well as amusing.
