Twitter screen names aren't immutable -- they can be changed over time. Does anyone know if an old tweet references a screen name and that screen name changes ownership, does the reference to the screen name change within the old tweet?

Not that I have seen. This account started life with a different account name, which is why my creation date is way before my first tweet. If you search the old account, you’ll find the old tweets still under the old name. Same user ID.

Feel free to use my account as a test bed for it if you’d like.

Is there a limit to the number of times someone can change their screen name in a certain period? I need to look that one up. If Twitter treats user mentions as specific people, then I'd consider this a bug because older tweets can have the associations break.

Hmmm I may need to look at this again myself, or maybe something has changed. A quick search of the old user name no longer pulls up the tweets under the old user. I’ll search this account once I’m back in front of a machine.
