GoDrop.it!

Calepin reads Markdown-formatted, plain-text files stored in your Dropbox and converts them into blog posts for you. You can publish, edit, re-edit, and delete posts just by editing these files and then re-publishing your blog. Calepin does the work of converting these plain-text files into a useable blog, and even generates an Atom feed to allow people to subscribe to your blog in their favourite feed-reader, leaving your free to concentrate on writing.
