I went through several pages of the fly swap forum this evening trying to determine what had changed. I read several threads of swaps that I had participated in and several that I had not. One thing that struck me was how may more active participants there were on the board. Even with many more possible participants most swaps took at least several days to fill. With many fewer people posting regularly it takes a greater percentage of those people to fill a swap. Looking at those swaps I did not join, some had themes that did not interest me, some seemed to be filling with simple or uninteresting flies and others I might well have joined. At this time I can't remember why I didn't in any given swap but work hours or other commiments may have contributed. One thing that was clear was that some of the people who had joined a lot of swaps at one time were active in the swap of the month before that too seemed to disappear and were not usually doing other swaps.
