Say what you will about Mormon/LDS religious beliefs, but I have never met anybody more selfless and pleasant when it comes to volunteering and caring for those in need. I've been a recipient of that kindness and co-participant in many volunteer activities with them, and not once felt like there was any attempt to push a belief on me other than "be kind to others". I probably wouldn't want to join them at church or read their literature other than as entertainment, but the individual people don't deserve all the hate that the church gets as a whole.
A short response to the reactions your comment received:
I'm not sure why so many took your comment to be negative. It looks like a plug for that church.
I was disappointed to learn the nature of the volunteer.gov sight. I don't know why I expected different from a .gov url. It is obviously useful to know who is behind an effort. So your post added useful information.
I have used justserve.org to find opportunities to serve in my community. Most of the activities I joined didn't seem to benefit the church in any way beyond a rising tide lifting all boats. I jumped in because they looked like worthwhile activities that would just take a couple hours of my time.
So I took your posting as a bit of good will for an organization committing resources to a website that lets people of any stripe find opportunities to help other people of any stripe.
