Based on raw download stats:

basic-prelude has probably received the most traction. It has ~8k downloads.

classy-prelude decays to ~4k downloads.

general-prelude ~180.

The other two I mentioned have had ~100 each.

By way of comparison something like, say, 'profunctors' has ~50k downloads.

That is interesting, thank you for sharing! Are you using direct downlaods of profunctor? because profunctor is designed to be a library dependency (lens depends on it as do 20+ other packages), whereas with classy-prelude users are advised to not use it as a library dependency and only use it for their applications. There is only really one library with usage that depend on classy-prelude, classy-prelude-conduit, and only classy-prelude-yesod depends on that, and nothing depends on that, they are all designed for application writers, not as library dependencies.

Does it makes sense to make a direct comparison of total downloads for these 2 different use cases?

That said, I spend an awful lot of time talking to people at conventions and hackathons, and my response was mostly anecdotal based on responses I've received as I've asked around to find out what people want in the Prelude going forward.

How do you know if alternate prelude are gaining traction? Libraries authors are always going to hesitate to include another package, but they are really for application developers. Are you using download statistics?

Note: we already have several of these alternate Preludes out there, which have gained little traction, largely because many users aren't willing to incur another package dependency for convenience.
