I think that specific forum is quieter because of the 26,000+ Registered Members worldwide, we don't have a preponderance of collectors visiting that are specifically into pistols/revolvers other than the Model 1911 genre.
The other factor is there are far more "takers" then "contributors" in most any type of forum on the Internet. By that I mean, folks who simply go to a site to read and research, as opposed to answering questions and helping others. As an example, not counting Google or other type of search robots which index threads from the site, our daily/monthly/yearly site visit activity is actually up over 30% this year, even though we're just coming out of the summer, which is traditionally slower.
We've had 4,813 different "real" people visit the site in the last 24 hours who spent an average of 15 minutes searching and reading threads in various forums, but only about 450 of them posted anything in the same time-frame.
I've spoken to many other gun site operators and from those conversations, I do have the impression that our hobby is generally in decline, with less new collectors entering it every year and the old guys like me (67) starting to fade away, to use a polite expression.
Perhaps it's getting too expensive for younger newer collectors, or maybe it's just a fact of a changing culture.... I really don't know for sure.
For those that are interested, there's a lot of site empirical data available in our statistics section, which is accessible from our Quick Links drop down box menu at the top of the web site on the navigation bar.
Site Statistics (click here)
Once there, look at the bottom of that web page display and choose various statistical screens to view different types of data.
I've attached a couple of screen pics below which you can all view anytime from that member menu and as examples, it shows the current status of our most popular forums and a snapshot of current member demographics. Keep in mind that the member demographics doesn't show all 26,000+ members ages, because the software is only able to analyze the data of those members who actually enter their birth-dates and ages in the optional member profile fields.
