So there are a few users on here that have some really good knowledge about certain sports. You get pretty good quality answers - these guys are generally coaches or referees in their respective sports and honestly most of the really knowledgeable people don't have a lot of answers on here.
Then there are a few users on the site that you can tell (by their comments and secondary information) that have little to no expertise on the questions they are answering. Their answers vary from not right at all, to kind of right but totally missing the point.
These same users will down vote good answers that aren't theirs (I have tested this out multiple times with multiple accounts - I do not have multiple accounts, another user helped me test this and it was very easy to test). Then they will answer the same question with something close to what was downvoted - and sometimes it is funny that they will answer it (googling things but then misinterpret most of the facts to the point the answer is wrong).
This never gets fixed and we have a large degree of answers on this site that range from bad to wrong - these have upvotes and are accepted. What is also telling is that I belong to a couple of officiating forums - basketball and football - and there is a general disdain on those sites for this site. These are users that have no idea I even post on this site, and they basically treat this site as nothing - or answers from kids.
So the DIY SE site has a lot of answers from contractors, electricians and builders. The mathematics site has a lot of answers from teachers, professors, and engineers. Where does this site get it answers from?
A big problem on this site is the moderation. The mods only involvement are to enforce "play nice" rules. On other SE sites if there are poor answers the mods step in and comment or try to encourage site to have good answers. Here the mods allow a small group to up and downvote answers to fill their tally - we all know it is going on.
So "play nice" is only for those with the maturity to directly discuss things on the site, not for the people in the background working passive-aggressively. Good job SE and mods!!! It looks like the robotic rules do not work with a small captive user base.
Do you need examples? How many do you want? Do you want me to just name names? Are the mods/SE happy with a site that is this poor and has so many misinformed answers?
Recent Example: Why do teams leave ~4 seconds for a field goal attempt
The accepted answer is wrong - categorically. There has never been a timeout in upper level college or pro football in the past 30 years with 4 seconds or less on the clock. The answer reeks of - let me think this one out - not actual football knowledge. He even said that the kicker/holder can spike the ball. What? That is grounding. Joke. Upvoted/accepted. My correct answer downvoted. How is the site not a joke to new users?
Basketball - Blocking and Catching Shots - Accepted answer ABSOLUTELY WRONG - common knowledge wrong. My small kids know that a block gathered is a block and rebound on stat sheet.
Is a hard slap to the basketball a foul? - A right answer by me downvoted by three users and two users that are referees commenting on why would this be downvoted. Notice how these two guys, who are referees, don't answer many questions on the site? Why would they?
And might as well shut the site down because it is way less accurate than Wikipedia Example:
Does the defense have to defend the extra point? - 7 years and an absolute wrong answer has 15 upvotes. No mods commenting about the wrong answer. During those 7 years this has played out multiple times with the NFL referees making the defense get back on the field.
Note: Thanks for the downvote on this question/discussion. It's apparent that attacking me is more important than having answers on this site that are correct.
Update: Really odd that none of the mods on this site have wrote an answer about any of my examples. This has been open for a month and zero from the mods.... Yea I quit answering questions on the site too.
