What’s up with this?
When somebody copies and pastes a status to do a RT, the display_url winds up in the clipboard. It seems twitter assigns it an entirely new t.co and pic.twitter.com link. But the status entities are showing the original t.co link, so I can’t regex the status text to update the shown URL.
Let me guess, that’s what indices are for? And I have to keep track of shifting positions after each replacement? No!
