Parodying the Facebook name, TheFlankBook does what the popular networking site does and more. Using an open source variation on the mega-site, the home page brings up a news feed of sorts. Showing public posts from the users, where all sort of things – but not limited to – pony related news is being posted in a collaboration of sources from all over the fandom.
With a straight-forward navigation style on the top featuring a chat and other valuable links, you can find anything you might want to look for within a couple of clicks. On the sidebar there is even a music player featuring music from the show and remixes of those songs.
