Great news: Fluentd will be at RubyConf 2014 next month! In fact, if we count our sister project Norikra, there will be not only one but TWO Fluentd-related talks at RubyConf =)
Many of Fluentd's core contributors will be at the event. In addition to the two speakers @tagomoris and @kiyoto, the main maintainer @repeatedly will be hanging around to answer your questions.
Happy log collecting, and we look forward to seeing you in San Diego!
