As the proofreader for anything that Blogcampaigning's other team members write in English, I keep pretty busy and don't always catch their mistakes. Sometimes, I'm not even aware that they have made mistakes. Hell, I probably make quite a few mistakes myself. Fortunately, there are people out there like Ian Ketcheson (via Tamera at 3i) to keep me on my toes when it comes to the English language. Ian's recent post on social media being plural rather than singular is a lesson for all of us.
Hopefully, Terry Fallis and Joseph Thornley won't feel bad about their PRoper English turf being stepped on.
