There is nothing off-topic here. I'm trying to show what people do and what people prefer more. This is a very good information, if you see more migration FROM and less TO, it means people get rid of this forum platform.
This means we've migrated 26 forums from X platform to SMF, but SMF loses 55 forums, they have migrated to other forums.
You can find more info in gConverter Forum Migration Statistic page: https://gconverters.com/statistics/I'm guessing he only seen the image and not the actual site.
