As @SABOTEUR pointed out, I have written about this on other questions, but let me try to succinctly say what I like about the site.
1) You can say whatever you want, you just can’t attack anyone.
2) If someone gets out of line, the mods are available 24/7 to do whatever is necessary within minutes.
3) There is no expectation that lurve will ever be worth anything, nor is there a “leader board”, which means that no one competes, no one withholds lurve because then that person might get a better score, no one can take lurve away from a person to retaliate, no one is setting up fake accounts or colluding with others to artificially inflate their lurve score, and even if one tried to do this for whatever reason, you can only earn 100 lurve points from any other single user…as such no one here is trying to compete or game the system and lurve feels more genuine and real than points, because it is freely given as the spirit moves a person to do so.
4) Unlike other sites where I could go through dozens of pages of questions before I found one of any interest, every day questions of interest are posted, and even the questions in which I’m not interested are intelligently phrased, thoughtful and not rife with spelling and grammar errors, because the mods strive to create this type of experience for the users by eliminating chatty questions, poorly spelled or phrased questions, duplicate questions, stupid questions, joke questions, self promoting questions and rhetorical questions. The questions you see here are a legitimate attempt to start a discussion or to solve a problem.
5) Unlike other sites, the first few answers to any question are expected to be serious, in order to give the asker a chance to get his or her concerns addressed, before people start to crack jokes, but once a reasonable amount of time has passed and/or some good answers have been posted, then you’re open to use any sort of humor, language or whatever, no limits, you can have fun, it’s just that the mods recognize there is a time and a place for fun and games and a time and a place to be serious, and though that may seem like over-modding to some, it really creates a site where you can expect quality in every discussion.
6) If you’re politically liberal (as I am), you are in the vast majority on this site. If you’re atheist or agnostic (as I am), you are in the majority on this site . This site is full of people who think and believe the same way I do, with similar values and ideals. However, if you are not these things, you will also find that people here are open minded, and willing to hear you out. Everyone can find himself in the minority here on one issue or another, but no one tries to stifle dissent, dissent is actually cherished here, as an opportunity to explore other ways of thinking and to give fodder to conversations and intelligent discourse.
7) People will honestly and openly disagree with you, and will support their arguments for the most part with intelligent, fact based discourse. You do not find that this site attracts the type of person who just wants to win the argument at any cost, and if one stumbles on this site, they are usually driven away quickly, just by virtue of the fact that people here can sniff BS a mile away and know what to say to diffuse it.
8) Because unlike many sites, this one is not designed solely to make a profit, not only do you have a lack of advertising, but you have a lack of attitude on the part of moderators. Whereas mods on the other sites treat you like an annoyance if they need to step in to mediate a dispute and would rather let you hash it out yourself because time is money, here the mods make nothing save for a small commission if someone links to Amazon through here and actually buys something…they basically volunteer for the job and do it for the love of the site and what it represents.
9) The creators of the site actively solicit feedback from people here and genuinely care what you have to say.
I could go on. I love this site, and I think what it boils down to is this. There is no other place on the internet (or in real life for that matter), where I can attain this high a level of honest, intelligent and open discourse on this broad of a base of topics. I feel the advice and answers I am given are intelligent, well thought out and useful, and I get to see the world from a variety of points of view. I never feel that I’m arguing with a brick wall when I encounter someone who does not see eye to eye with me. I feel that I am a trusted and respected member of a community. Bottom line, for me, this feels like home…it’s some place I’m compelled to go several times a day. And I wasn’t wild about some of the moderation at first. I too asked my own “is this censorship” type question way back when I first came on board and was a bit taken aback by being moderated. But when I realized it’s all about quality, and that mods were always willing to listen to my concerns and discuss the issues until we found common ground, I felt a hell of a lot better about it, and I can honestly say I have no desire to check out any other Q&A site.
