In the spirit of sharing, and because lots of other cool people are doing it too, I'm going to donate CDN $1 to charity (most likely going into the pot at gifter.org) for every comment someone leaves on this post.
That's all you have to do. Leave a comment on this very post. It'll take you about 15 seconds and won't cost you anything. This is not a scam, and I'll post the results here once it's all done.
You know what? Let's make it even more interesting. In your comment, tell everyone a secret. It can be vague or descriptive, anonymous or not, whatever. For every secret someone tells the world in the comments on this post (one per person), I'll make it $1.50.
