We had an amazing Drupal meetup in Santa Monica a few days ago (link). Our turnout was much higher than it has been in quite a while (atleast 40 people showed up) and the atmosphere was very cheerful. Organizers like Steve Rifkin and Ishmael Sanchez have added a lot of positive energy since they joined and their efforts clearly showed last night. We had two presentations (I was one of the presenters) and two lightning talks - The other main presentation by Ishmael Sanchez and both lightning talks (by Justin Gossett and Chris Charlton were simply fantastic.
As part of a lightning talk, I did a lightning talk at a Drupal Meetup in LA on the Field Collection module for Drupal 7. For those that do not know, Field Collection is a successor to the multigroup module in CCK from Drupal 6. It allows a user to associate a grouping of fields as one field to for any type of entity (including another field collection so you can have nested field groupings inside other field groupings).
