bigpaper is one page shared by everyone who opens it. Whatever you type appears for everyone else straight away, and you can see their cursors moving around too. There's no sign-up: you get a random animal name for as long as the tab is open.

Nobody can wipe it. You can erase up to 40 characters at a time, everyone has a little ink that refills as you go, and text that has been on the page for more than ten minutes is settled: the first eraser only fades it, and it disappears once a second person erases it too. Fresh typos are easy to fix; finished work is protected.

No links, no slurs. Be kind, be weird, leave something nice for the next person.
