A post by Alex Popescu, Data Scientist Summit Videos, lead me to discover the Greenplum Community.
Hosted by Greenplum:

registration (free) brings access to the videos from the Data Scientist Summit.
The “community” is focused on Greenplum software (there is a “community” edition). Do be aware that Greenplum Database CE is a 1.7 GB download. Just so you know.
