This is the crux of the issue. There are really two mostly distinct groups: People who are mainly interested in Monero and people who are interested in Monero but only as part of also being interested in other coins (especially Bitcoin, but not exclusively). A separate forum is obviously great for the first group, but much worse for the second group.

Do we have any market research as to the relative sizes of these groups, or projections how that might develop in the future?
