Well, I am going to take the unpopular side of this and defend the listserv. I disagree that the listserv is composed of only elitists and those who love to argue. There are alot of truly good helpful people who frequent the listserv and offer alot of advice and experience to others. Unfortunately the listserv is unmoderated and as anything that involves a group of people you will get that 1% that makes the most noise and gets the most attention. I have spent alot of time formatting the old listserv archives and making them searchable so I have read alot (almost 10 years worth) of the posts and have found an incredible amount of information available in them on questions I did not even know enough to ask. Do not write off the listserv because 1 or 2 people want to argue about something, ignore them (which drives them crazy) and read the information that is being made available. And try to understand some of the people who post there are the same people taking their time to go climb the tepuis to discover and identify new species and get them into cultivation, they probably do not have the free time to answer on why you cannot use tap water on your vft, not a criticism on the question itself it is just that that information is easily obtainable from a hundred other locations and they will spend their time on something not so easily obtainable.
My two cents & Cheers,
