I wonder exactly how SC links appear. There are so many buddhist forums on facebook, and such a wide variety of people interested in ‘buddhism’.
My initial thoughts were that the large number of visits from FB were just the result of vaguely interested people clicking on links - and that they were not really interested in the objectives of SC. As such one would expect a much smaller percentage of retention among this group. More or less ‘random’ clickers or tourists just having a look
So if you really want to ‘capture’ their interest and involve them in sutta study it would require some serious efforts to be expended. Personally, I’m more interested in existing Buddhist communities, that already expend a lot of effort following the teachings of the Buddha, getting access to accurate teachings via the EBT’s
So I’d say the goal with the FB cohort is to introduce them to Buddhism at a more serious level, as compared with providing accurate information to Buddhist practitioners.
Of course both are laudable, but may require different approaches - just some thoughts…
It would be interesting to have a look at what page they landed on, as you suggest. One of the issues that keeps coming up is the difficult of navigation and search in SC. This is certainly an obstacle of increasing difficulty, the less familiar one is with the material. So this may well have a significant impact on usage and retention of inexperienced users.
