I can see specific tweets of the form https://twitter.com/<$USER>/status/<$ID> https://twitter.com/<$USER>/status/<$ID> but not https://twitter.com/<$USER> https://twitter.com/<$USER> So it seems that links to old tweets would be readable, but it's difficult to discover new tweets without an account.
