So I was very glad to have some research to back up my feeling that a writer is taken less seriously and may suffer from a lack of valuable exposure when he or she doesn't show readers the respect of careful proofreading:
Blogging is fast, informal and easy to do. Spelling, grammar and factual errors happen - but do they make a material impact on the success of a blogger? A small but interesting survey run by crowdsourced copy editing service GooseGrade concludes that they do.See the results of the survey here: Errors By Bloggers Kill Credibility & Traffic, Study Finds
Approximately 200 respondents told GooseGrade that while blogs aren't a major source of news for most of them, they often find errors on blogs and that makes them less likely to share the content they find there with other readers. While unsurprising, these numbers are a good illustration of just how much things have changed in media - or not.
