An incognito window let me watch the whole 25 seconds with the user writing something and three book writing back, but I don't know if my IP or incognito cookies or anything else are special.

It would be ironic if you have to actually sign out from Twitter, not just use incognito mode, to bypass the signup nag. Or if they mark IPs as “signed up” or something. Thanks.

Thank you. As someone who tweets, this is helpful to know.
