This is a very interesting topic and the smaller traffic on this site is not necessarily unique to just Gasgas rider. Forums in general have been really gone downhill IMO in the last couple of years. Some seem to have almost dried up all together.
Not sure the reason why, but I'm sure social media plays a role.
For me, it's frustrating because I used the forums to learn, and try to pass on valuable information that can be used to help with riding, maintenance, bike reports, ride reports, gear, tuning , etc. I received tons of great advice from guys who actually rode over the years and enjoyed posting.
Now, the forums have become less about that and more like, "Facebook for old guys". More opinions and arguing over stupid stuff than ever before. Threads constantly derailed by "well, you're an idiot if you do that". It's less here, but it's definitely something that is prevalent. You look at these guys profiles and realized they are older guus who don't ride much, but spend all day on these forums spouting off their opinions.
I hate social media and refuse to take part in that mess, so I guess I'm stuck to just riding and sharing information with my buddies who actually ride and have a passion for our sport.
Just my observations over the past couple years. Yes, Rod did a nice job on here with keeping everyone up to date. Just not sure forums are the future of communication.
