Below is visualization of the email discussion around the topic of the infamous (in some circles) httpRange-14 decision that appeared on the following w3c discussion lists: public-awwsw, public-lod, public-rdf-wg, public-swbp-wg, public-vocabs, semantic-web, www-tag, public-swd-wg, public-sparql-dev. Each node is a person (hover it to see the email address), and edges indicate where there has been correspondence. Blue nodes are people from the w3c. If you want to see the data that drives the app checkout the RDF serialization or the JSON that drives the D3 visualization.
There is also a similar thread-oriented view of the email discussions.
