There are many reasons for slow forums. Running one of my own I see seasonally slow times and peaks however even though it is a niche site for a specific group of people I have noticed over the years that my traffic mimics those of the open public forums. There are many other forums out there and as mentioned, Facebook groups and media such as YouTube. The product has changed. People lose interest or no longer own relevant vehicles and have no reason to participate anymore. The bottom line is that with all of these changes any community must be run like a community that fosters communication and offers good content to remain desirable. I don't believe The Diesel Stop has lost it or will disappear any time soon however things have just gotten a little bit stale IMHO. Bottom line, it is what you make it - that goes for the Administrators, the Moderators and every single member that participates in this community.
