It's good to worry and consider this phenomenon some, I have had the same thoughts in the recent past.
This is a rather new site actually. It started somewhere around 2004 so about 10 years old, slowly it grew and as new members came the posts count grew. People were interested to get to know each other, either just on line or in person, either way, that takes communication, so posts were created and BS bloomed. I think we have got quite comfortable with each other and have added more challenges to life, so that will take time from the other things we do with our lives, so VentureRider.org might become a bit more passive rather than active.
Yes I think that keeping things on an even keel may have a little effect on some considering not to post, just in case that they may be stirring the pot in the wrong direction, but I do believe that keeping things civil has a more positive effect and generates a better relationship between us.
And as mentioned, things change, and so does life and the needs it brings with it. So if we need it, we tend to use it, but if the need diminishes then so does our use of whatever we were in need of.
In conclusion, I think that if more folks were to make regular use of SeaFoam, they would find less need for CTs, and that would translate in the need for less oil changes. Now if you don't need to change the oil as often then a person would have time to listen more to the cassette deck. So if you've never used it before, now is the time to consider getting a supply of Fluid Film, before the price goes up again.
THERE, happy now?
