This one grabs the buffer contents, converts it to HTML, and sends it to the clipboard for pasting into WordPress or whatever.

" Send Text Through Filter To Clipboard:
" http://vim.wikia.com/wiki/Use_filter_commands_to_process_text
function! MDC()
:redir @+
" No output file specified so it goes to STDOUT
exe '!pandoc %'
:redir END
endfunction

This morning I was monkeying with using Python in Vim to do this. That also works. Then you can use Python's Markdown module.
