This especially. I noticed a while back that Opam seems to have dropped usage information from the packages, and now even opam.ocaml.org doesn’t allow viewing the number of downloads of a package or sorting packages by usage, which is especially useful information when choosing packages to install. I’m not sure if keeping this metadata is difficult and that was why it was removed, but it was a particularly important feature.
With respect to the community section, it seems to be missing the discourse and mailing lists (I understand that the link at the top links to the discourse forum, I found it easy to miss).
There was an exchange on the mailing lists about how OCaml users with visual impairments often find mailing lists more accessible as compared to the discourse forums, so I guess the inclusion of a link to the mailing lists would be a good way to make the community more inclusive to developers with visual impairments.
