For this particular forum, I think dialog is important even if it seems like we may be repeating the same conversation. I think dialog is an important part of the learning process. I don't think it's sufficient in this forum to simply say "search the forum for previous answers". I think a lot of learning goes into just forming a question and writing it in your own in your own words.
For example, I suppose if you teach the same class for years you get the same questions over and over. That's ok. That's the reason that someone takes the class so that they can get the opportunity to asks questions on a subject that is new to them. Remember it may be old news to some of you ranch hands and more experienced cowpoke, but it may be new news to the greenhorns. And remember this is a "friendly place for Java greenhorns".
