I noticed too, but rather than blaming the newer posters who are still feeling the way into the forum, I blame the lack of participation of many key members. I know they're on the water and I know they're taking sweet pics, where are the posts???
Mike, you are correct about the latter lack of participation, but isn't it a chicken or the egg scenario? Did lack of participation allow the void to be fillwed with chatter, or did the chatter cause the lack of participation? I made a concerted effort to substantially decrease my participation, including moderator status (but I just noticed I still have it in two subforums?) because I was not enjoying native fish or the association. I spent my entire time getting worked up over a few bad apples and dealing with them, potentially being in conflict of interest due to my employment with a Natural Resource agency depending upon the wording of things on the board attributed to me, seeing some lax ethics, and people asking for the world but not willing to contribute an hour or two of their week unless it got them some diret, and somewhat selfish, benefit. On top of that, my work load has increased 50% while the staff I work with has decreased, along a general and literal sense of having to justify your job on a weekly basis while cuts to a department that makes up like 1% of a state budget continue. So yeah, I don't post much anymore, and now half of what I see has poor titles making it a crap shoot whether or not to read or little to do with native fish and more to do with basic aquarium care that can be answered in any basic book if someone took the time to find out the answer for themselves. If I had any shred of time, I could be feeing AC with an article an issue about natives in Maryland.
On a more cheery note, our group (Maryland Department of Natural Resources - Monitoring and Non-tidal Assessment) has undergone a major website change, including some (basic) interactive maps about stream condition and life, fact sheets, reports, posters, news, and many more things about the fish that can be found in mid-Atlantic streams.
