My tuppence worth.
I can understand exactly where at240 is coming from.
OK, my perspective - I've been on this forum for ten years now and have answered nearly every question that has been asked, time and time again and I'm at the stage where I'm quite content to let others answer those questions. They have learned from us and to quote a phrase "I have taught you well, grasshopper."

I visit V-Flyer daily - several times a day, if the truth be told but I really can't be bothered getting my head around such new developments as the timeline for seat selection and the tie-up with Delta. In addition, my recent trips have not been on VS for the simple reason that they are not VS destinations and as a result I have lost my Gold card. Indeed the change in re-qualification was the beginning of the end - no more Gold runs or that extra trip when there was a fare sale. Oh, and let us not forget the forces of nature that swamped my home and forced me to rob the piggy bank known as the Honey Lamb Holiday Fund to shore up the shortfall from the insurance company. As a result price, rather than airline has been the driving factor when booking flights although VS is my first port of call. So I let the current frequent flyers answer the questions.
Finally, sites like VF to succeed must be organic. A couple of years ago there were complaints that is was "clique-ish". It was a fair comment. There was very little movement. Newcomers joining the site found that there were so many "in-house" comments flying around that they felt they were invading a private party. References to Hull, my gin in-take :w and my disaster-prone flights abounded to the extent that they felt unwelcome. That appears to have gone and what I feel is happening is that there is a new generation of V-Flyers who are forming the same kind of friendships that occurred in the first wave of VF. I think HWVlover summed it up succinctly when he posted

I guess it was ever such. People do change their airlines of choice so don't have as much reason to be on here. Plus of course, people who were prominent on here, in various ways, might well be (or are) more active these days on other social media, specifically Facebook.

That is exactly what has happened. While we still touch base here, because we have formed friendships courtesy of VF we no longer need VF to sustain that friendship. The current crop of V-Flyers will find the same in the course of time and hopefully more will follow on behind them in the next wave of posters
