I'm a little on the fence about this. Of course I support the meaning behind it -- raising money and awareness for ALS...but my problem is how some people (cough mostly celebrities cough) use this as an opportunity to sort of promote themselves.
I've seen many videos where these people just don't even mention ALS (let alone how/where you can donate), and to me that's completely missing the point. This is not to show how cool you are (no pun intended), or how much of a good sport you are, yet a lot of people seem to think that's what it's about.
I have a lot more respect for those who don't throw the bucket in a video, but specifically push people to donate.
Grump mode off.
