Script Summary: Adds nested replies to every Twitter conversation thread (updated 27th Aug, 2010)
Nested Twitter Replies looks for the phrase "in reply to [user]" and recursively gets all replies to display the conversation thread as a nested block.

This script can easily break when the Twitter HTML changes, so be sure to check for updates. You can contact me @pratham for feedback.
