This blog CAN make a difference.
Check out the email I just received from a friend from high school:
As you may or may not know, I am a technical writer. I showed your blog to my coworker (she thinks it’s hilarious), who showed it to another employee of our firm. This employee works weekends as a bartender at the Hong Kong and he emailed a link to the Grammar Vandal Hong Kong blog entry to the owner of the restaurant. Hopefully the sign will be fixed soon!
Don’t let anyone ever tell you that you can’t change the world!
