I would like to use Haskell more for my projects, and I think if I can get started using it for web apps, it would really help that cause. I have tried happs once or twice but had trouble getting off the ground. Are there simpler/more conventional (more like lamp) frameworks out there that I can use or should I just give happs another try?
Here is a list of web related blog posts about Haskell: http://haskell.org/haskellwiki/Blog_articles/Web.
Furthermore, the next big Haskell web framework is WASH: http://www.informatik.uni-freiburg.de/~thiemann/haskell/WASH/.
And there is an Apple webobjects based domain specific language: http://www.cs.uu.nl/wiki/WebFunctions/WebHome
You can use CGI and an (x)html combinator library, as in http://www.haskell.org/haskellwiki/Practical_web_programming_in_Haskell. A larger overview of libraries, frameworks etc. for web programming in haskell is at http://www.haskell.org/haskellwiki/Applications_and_libraries/Web_programming.
If you decide to go with HApps you'll probably want to checkout this excellent example driven tutorial that is being developed as a HApps application: HApps Tutorial
There is also Hope: http://hope.bringert.net/about although it doesn't seem to have gained as much traction as HApps and WASH. The site has also been quiet for about a year.
