The talented Shimon Rura just launched a new service called tweet and shout: music people are talking about. It mines Twitter to find bands and musicians that people are talking about, and provides the number of people and tweets and cross-references with the Amazon sales rank.
What’s refreshing about Shimon’s work is that he admits the service isn’t “groundbreaking or thought-provoking.” But he does point out the interesting things, including the facts that the service provides context to otherwise unconnected conversations, and the fact that the service puts faces to fandom.
