[Haskell-beginners] happstack versus yesod

[Ramy Abdel-Azim]

well, i'll add my $.02 here (hopefully without throwing fuel on the fire)
and say that - without knowing much about either, I asked the question for
pete's sake! - is that from what you're saying, if I'dlike to use one of
these frameworks to not only build my website but to also solidify what
knowledge of haskell i've acquired, I should go with Happstack.
