Quotably reformats Twitter messages into threaded conversations, making it significantly easier to follow actual discussions that are occurring on Twitter.
Prior to Quotably, it was hard to follow conversations, even if you are in the middle of them. Sometimes responses come back tagged with your user name (@username), but often they donâ€™t. And if you are just observing the conversation it is nearly impossible to see all of the responses.
The service is easy enough to use - just tell it a Twitter ID and it will show you threaded conversations that involve that person.
