1) Wealth of knowledge- I have learned alot here!
2) People- the people here are great. If there is a problem, it is handled maturely
3) Diversity- I love hearing about horse communities in other countries!
And last but not least
4) Maturity level- compared to all of the other forums that I am a part of, this forum definitely has the most mature people on it. I love that a discussion can be handled like adults.
