Twitter.com is heading for some changes with a new search feature that is going to crawl posted links on twitter and index them for search. This is going to create a real-time search engine that will allow users to have better access to the live conversations and sites shared on twitter. According to Loren Baker in the Search Engine Journal, twitter is also going to be launching a reputation ranking system that will somehow consider the twitter rank of the people who post the tweets. Twitter has not released how they will calculate this twitter reputation.
