One day before the deadline of the CfP I have created a tag cloud of all conference submission abstracts that reached us so far. During last week several more proposals have been sent in for Buzzwords. We have submissions from core developers of relevant open source projects, e.g. HBase, Lucene and Hive. There are talks both from people working themselves on open source projects but also from developers using the software. After the call for presentation is closed, we will publish updated version both of the tag cloud and the graphs from last week. If you yourself want to influence the graphics: Submission is open until April 17th.
