I feel any real load could kill the server though (or your AWS budget!), so maybe trigger the save when I stop typing for half a second. Seems to lag a little when I type quickly.
I'd like to be able to save certain URLs as different versions to share. Could come in handy for collaboration or editing too.
The plan is to eventually use websockets ("magic") instead of foolishly POSTing, but is it possible that watching 'input' is the real mistake here? Perhaps I should just save every two seconds (or half second, as you suggest).
What would you suggest about saving urls? I couldn't think of anything easier than just bookmarking.
IMHO POSTing is fine, but you definitely want to wait a couple seconds each time.
