I try hard to avoid combining sociology and coffee (the last thing I or anyone else needs is forum participation as "fieldwork"), but sometimes some tidbits of the trade come in handy. A common distribution of seniority in jobs or membership time in groups is bimodal, lots of newbies, a middling group of long time members, but relatively few people in between. This type of age distribution is generated if the survival rate (i.e. the probability of being around for another day, month or year) is proportional to the prior length of membership.
I would not be surprised if the distribution of membership length was like this for HB and other fora. Most people who join up have a short term agenda, to get buying or fixing tips. People needing operating tips may stick around a little longer. For a few, membership turns into a coffee and espresso hobby; and they become the long time members. But even hobbies compete with other hobbies and real world necessities; so hobbyists eventually drop out too. For them the length of membership is an indication of how much they have invested in the coffee hobby, and how much longer they are likely to be here.
If this survival curve holds, then Jack is right: while newbie noise may be annoying, it's also self repairing.
