I see it differently. I see a public, on-line forum where people who are interested in coffee have a place to share opinions, ask questions, learn, etc. I see a history of "newbies" having a go, getting stuck, trying to search (hopefully) the rather large amount of info available on line, and asking questions. People can choose to answer or ignore. The best clubs and societies I have been involved with are always happy to help new-comers, even though their questions have often been asked many, many times before. But I think part of being a member of such groups is being willing to share knowledge when possible, and realize that no-body knows it all and there is always more to learn and discover. I think to make good coffee (especially espresso) requires good coffee, good knowledge applied correctly and good gear. It would make no sense to me to separate two of the four Ms.
