I've been on Pinside for a few months now. And I always intended to donate, but never seemed to get around to it despite my daily visits to the site.
I finally did, and challenge you to do the same. Didn't break the bank or anything--heck, I only ponied up $5 for my first go-around.
If you've been thinking, "I'll do it later."...well... do it now! If you've already donated, this would be a great time to do it again!
