Tweet Scan is useful for finding replies that Twitter doesn't or for easily following topics and conversations you care about. There is another feature that people keep requesting, and it's a pleasure to fulfill that request. People(you) want to be able to search tweets by themselves or another user. It's like searching your own email, a must-have feature.
Testing it has been a lot of fun. For example, I wanted to revisit the link codinghorror posted in this post but there was really no good way to do it before now. With a simple search for "mouse" by "codinghorror" it was quite easy to find.
That's why I present to you the ability to search posts by user. Try it out and send a shoutout to @weex or just mention tweetscan if you like it. Happy scanning.
