I’ll be the first to admit that my grammar’s not always perfect. In the rush to get things written, sometimes my brain disconnects from my typing fingers and something other than what I meant ends up on the published page. (My brain and fingers have some serious debates about homophones.)
But seriously, folks.
There is a difference between it’s and its.
There is a difference between your and you’re.
There is a difference between than and then.
There is a difference between there and their and they’re.
While you may dismiss some of those errors as a product of increasingly casual media or poetic license, not everyone does. Yes, sometimes it’s clear that, like me, your brain and fingers weren’t getting along. But it’s hard not to notice a consistent misuse of words.
What you write, and how, says something about you. Your level of care in how you express yourself often speaks more about you than the words themselves. It may not matter to you, but it may matter to people who matter to you: customers, prospects, friends, potential business partners.
So pay attention. And if you don’t know the rules—if you’re not sure—find out. Get it right.
