Our philosophy on this is pretty simple:
1. If the spelling and/or grammar mistake was made by a multi-million dollar corporation (like our favorite punching bag, Microsoft), be as harsh as you feel like. The logic is that such a company should be able to hire editors or proofreaders to catch the mistakes before they are printed or published.
2. If the mistake was made by someone whom you suspect has made an honest mistake, point it out courteously: “In the third paragraph, I think you should have written X instead of Y.” Adding a smiley also lets the recipient know that you’re not being antagonistic or judgmental. :)
3. If the mistake was made by a pompous, disrespectful, and self-righteous Grammar Nazi, see #1.
In general, less of this vibe
and more of this vibe
will benefit both you and the other person.
In closing, try your best to make your “criticism” constructive and helpful (or playfully humorous), not hurtful and demeaning.
How about you guys? Do you have any tips or suggestions about pointing out people’s spelling and grammar mistakes?
