What is the point of having a Q&A website dedicated to coffee? I wonder what could be the reason for stack exchange to host a website for a simple day to day task that looks so trivial. Is coffee making that hard?
Someone is new to the world of coffee, (it is not a day to day task for them and there are hundred of ways to make coffee from all over the world) and they  have a question about coffee. They do not know anybody who is knowledgeable about the subject.
They turn to the interwebs to find information. They do  a web search but there is so much crap and misinformation to filter out that a good and correct  answer is very difficult to find, so they think Gosh why don't i put up a site were  anybody can ask a question about coffee and those in the know can post answers to those questions.
The best answers will be voted on so they rise to the top and eventually a correct answer will be chosen. Misinformation will be called out and not allowed to misguide.
In the future if somebody else may have the same question and they do an interweb search on it, one of the search hits will be the Question and Answer  site where a correct answer was given to the very question they are wanting an answer for.
Perhaps this could work for All kinds of things
Even for questions with seemingly obvious answers like &quot;What is the point of having a Q&amp;A website&quot;
