I was writing a large post here in the /compose view and I left-click on a link, I didn't realize it so fast and BAM! The long text with all together is gone, unrecoverable.
I have 2 suggestions here: 1) Add a browser-based warning that you have filled out a form and want to navigate away (I have seen this numerous times!) 2) Add feature "drafts" and auto-save (AJAX) so your being-drafted post is not dead (and with last saved timestamp).
