We welcome people who have written (or plan to write) Haskell tutorials and exercises to post them on the School of Haskell, if they find its features useful. By now you've probably seen the Active Haskell demo in the beta screencast video? https://haskell.fpcomplete.com/beta
We also welcome good organizers (like yourself perhaps?) to write tutorials that consist partly or entirely of links to other materials. The role of editors and organizers is sometimes undervalued, but not by us!

Have you tried contacting the Haskell cafe instead? I am sure someone there will be able to get through.

And most of those are fast moving topics these days but they're well covered in blogs, the Cafe list, stackoverflow, they just need to be collated/cataloged. At a minimum some wiki farming would address a lot of those. Unfortunately, I emailed the wiki contact a couple times about pitching in and never got response.

JA Alonso has another book of exercises (in Spanish http://www.cs.us.es/~jalonso/publicaciones/Piensa_en_Haskell...
also the FP in Scala (Morris, Chiusano, Bjarnason) may include some haskell code, I haven't read yet, but definitely covers a lot of these hot topics
