Williams describes Tweets as "clues" in the journalistic process, praises its use as source-searching and research and "taking data and sifting the signal from the noise."
But he says it has only scratched the surface in what it can do for people. Its main goal is to find relevance for its users. He promises new list services to help curate content from participants on topics of interest.
Williams also discussed the balance between anonymity and trust on Twitter (the former useful in sensitive news situations, the latter necessary to build authenticity). He said Twitter is working on reputation systems to help build that trust.
