According to Harvard Business Review Editorial Director Justin Fox, it's those with the best command of the language. Citing the work of Panos Ipeirotis, Fox finds:
"Basically, the better the writing and the fewer the spelling errors in reviews of a product or a service, the higher the resulting demand for that product."Even negative reviews can result in higher product sales if the review is well reasoned and crafted.
That explains why online retailers such as Zappos pay dearly to improve spelling and grammar on their sites, Fox continues.
I dare say that most sites do not tamper with reader comments, unless there is some blatant libel or flaming going on. Editing dozens of comments can be time consuming and expensive, depending on the the price of your copy editor. But as this research shows, the increased revenue that results can pay for your editing bill.
I'm not arguing in favor of recasting sentences or other heavy-handed editing of your readers' prose. But correcting obvious mistakes such as spelling errors, changing its to it's, or their to there can go a long way to making your site more readable and engaging.
