Due to overwhelming popular demand*, BlogLiterately (version 0.2) has been released on Hackage.
It's a simple tool for uploading posts written in markdown and (optionally) literate Haskell to web logs. It relies heavily on Pandoc for markdown processing, but adds a few twists like syntax highlighting via hscolour. The original version was described here:
http://greayer.wordpress.com/2009/10/26/blogging-literately-in-haskell/
The new version (the first version on hackage) has been updated a bit -- to take advantage of Pandoc highlighting extensions and to support blog categories, mainly. The primary documentation is just the haskell package page:
http://hackage.haskell.org/package/BlogLiterately
It's only been tested with a WordPress blog (mine) but ought to work with any blogging software that supports the MetaWeblog API.
Send bug reports, etc. to me...
Thanks!
