@gvwilson
First of all, thank you. It's the right time again to discuss how to #leave a service like Twitter.
I'd strongly prefer to leave your Twitter profile open, though. Here's my reasoning. Past Twitter posts are sometimes not sufficiently bei Web Archives (yet). Findable, referable, potentially useful (you just never know, right?) public knowledge on the web shouldn't go dark. Yes, this is an issue of cultural heritage preservation, nothing less.
Thanks for considering!

@Lambo @gvwilson Re. identity squatters: Won't this not be a problem only for the people who stay on Twitter? I just deleted my account and don't see a big risk for myself. On thebother hand I am all for making the hellsite less attractive to so that more and more people stop using it. If more and more mentions lead to deleted or even squatted accounts this will definitely not be fun for those who continue using it.

@acka47 @gvwilson Please, let's agree not to delete online cultural heritage intentionally in order to damage a bad business model. Ultimately, it will hurt "them" only this much, but it takes away a unique piece of a common good effectively for everyone.
