Tweet Nest – An Open Source Application For Archiving Your Tweets
If you're using Twitter frequently, it is possible that you may have found yourself several times on searching for an older tweet.
However, Twitter usually doesn't archive tweets older than 2 weeks and the info shared/conversations become unreachable.
Tweet Nest is an open source PHP application that automatically archives your tweets and offers you an easy-to-use interface for browsing through them.
It can display the new-style retweets, geographic places and links to original tweets + includes thumbnails of media like photos hosted on common providers like TwitPic.
Tweets are categorized in months and a good looking yet simple bar chart shows the amount of tweets, retweets and replies you've sent every day.
