I keep joking to people that I want to start rotatedfloralheartbullet.com (.com), a social network where you're only allowed one character, but you have the whole unicode space to choose from.
Evan Williams founded Blogger (no character limit) and then Twitter (140-character limit). After rotatedfloralheartbullet.com's one-character limit, the logical conclusion is Bitter with one-bit posts. :)
