[Ixiaus]

I haven't actually tried to use multiple Stackage repos. I only think it's great because I helped a friend get started in Haskell and chose to see if Stackage would help with his cabal hell woes (it did and made the experience more pleasant).

In general though, I think stuff like Stackage is a community smell and has the potential for creating a schism and confusion in the community. If it's community infrastructure I also feel like it should be controlled by haskell.org and not a for-profit company.

I know I know, money and man-power are all issues but other OSS languages have successfully figured it out and I think Haskell can too.

I personally use Nix for everyday development.
