Communities are based around a strong common interest.
Will the number of people interested in your community’s topic rise or fall in the future?
A big fallacy of many product-based communities is they rise and fall with the popularity of the product.
By focusing solely on one product, and refusing to adapt, their popularity is limited to 2 – 3 years. That might be a year to get the community started, a year of good popularity and a year of decline.
It’s brave to spot a trend in the ecosystem and make a major change in the community as a result.
Your community might not like it.
They might need it, but they might not like it.
If you predict that the number of people interested in your topic is likely to shrink in the future, it makes sense to refocus that interest.
