I made this little program so you can view and link to a whole conversation from Twitter in context. Here's an example! Want one for your conversation? Just enter the URL of an individual tweet (it should contain a long number):
Example: A debate about congestion pricing.
How do I find a tweet URL? Click the text at the bottom of a tweet saying how long ago it was posted (e.g. "3 hours ago"). Then copy the URL from your URL bar into the box above.
Bookmarklet: You can use this bookmarklet on a Twitter.com tweet page to here automatically: twitter context
