It's no secret that spelling mistakes can cost your company millions.

But unfortunately, they are a common phenonmenom on social media, according to recent research by Brandwatch, who found that, in an assessment of over 1 million random mentions online, Twitter users are more literate than they were a year ago, they're still the least literate of all internet users, followed by Google+ then Facebook. (Perhaps it makes sense, given the 140-character limit).

The survey also looked at gender differences, finding that females use slang once in 169 words, whereas males do once in 192 words.Strangely, there seems to be a verb imbalance too; females use "so, lol, aw and oh" more often and elongate their words more often, whereas men tend more to shortening words like "gotta, kinda, wanna, imma."

Across the board, the most used acronyms are LOL, WTF, LMAO, OMG, and newly popular YOLO.

Those looking to save their company money may want to brush up on the misspelled words: "definitely, separate, embarrass, achieve and surprise."

Or simply implement a spell-checker; plenty are available online, including Speckie for Internet Explorer, Spell Checker for Chrome, while Safari has a built-in spell check feature (here's how to turn it on).
