I think most have touched on the various reasons
- for many that got on before, they got tired of the frequent reboots and failures, that are really a distant memory now
- for some they just don't have the time or interest to spend browsng another forum and reading threads and topics and posting. (They still prefer the old style email list where everything is sent directly to them. They are not all technophobes, they're intelligent and savvy web users, but just don't have the time or desire to participate. And no matter what aids the web site may have to enable this to work in an email list type mode, it is far more complex than joining the list and getting ALL posts sent to it, at least as far as I know
- even the old email list had relatively low participation, with far less than 50% of the members using it, and a small percentage of those doing the most posting
- facebook is another thing that takes some traffic away, people who use FB love it being their all encompassing communication tool. As an example my brother Richard (not picking on you bro) used to read the forum regularly and post too. Now when we talk about it he says he rarely goes there, but often sees MSTA stuff on his FB, or sees stuff from other MSTA members he's friends with on FB. I am not saying we should get rid of our FB page, but that has moved traffic over there. And many are not on FB, and I'm not going to join just because people have changed to using that for most of their communication.
As for what can we do to change it, I've said this before and I also know I've failed to follow through with my own local group. Sitting down with those who don't use the forum and showing them how it works, what is there, how to register, post etc.
Sadly I think it is what it is, the fewer posts the slower the traffic the less the regulars who post do so. When it gets slow there isn't much to talk about, or comment on. I bought a GoPro a while back, posted a thread asking for some advice, I got 2 responses and commented once after that myself. I know there are many others who are somewhat active on the forum with experience with GoPros or shooting video from the bike and was surprised there were not more replies. I'm not complaining or calling people out, but determined I'd need to find other sources for more info, or contact some people directly.
Really there are too many places, too many source, too many things to do and not enough time to do them. Or it isn't very enjoyable compared to other things so we don't do it as much.
