One day I'd like to have a LaTeX blog

Yeah, HTML is ok, but I'd really like to be able to write my blog posts in LaTeX. I'd like to be able to compose my posts in straight LaTeX, then upload them to the blog and have the server convert the LaTeX to some form that a browser can render. I'd also like to be able to push a button and have a PDF of all of my blog posts. Not that I've ever built an index in a LaTeX document, but I'd use that functionality to tag my posts.

Maybe one day I will write this software.
