No matter how many friends you have on Twitter, finding a specific tweet the day after you first read it is comparable to trying to find a needle in a haystack the size of Wembley Stadium. Unless you are using something like Twippr, that is.
Twippr is a search engine for tweets. And not any old tweet – it scours the ones that have been exchanged between you and your friends only. This turns the site into something really fast, too – its response time is as fast as only something that is really specific can be.
In this way, interacting with people on Twitter becomes something far more contextualized. You no longer have to say that you remember something for shame of hurting the feelings of your friends. Now you can find exactly what they are talking about, and have a much richer conversation with them. And Twippr actually lets you search the tweets that have been exchanged both with those you follow, and with the ones who follow you.
