This exists. It must.
If you're on facebook, you've probably seen the "I was green today" application. People complete the sentence, thus sharing simple ideas for becoming more environmentally responsible. I changed one more lightbulb to CFL today, and darn it, I want credit for that ;) The application is a great idea for reminding us that the little things really do matter, but why can't I embed the same application into my blog?
Come on, wise ones. I've poked around as long as my brain can withstand. Do you know of some utility that works for this?
