I was thinking of an alternative that would allow anyone to publish a meeting with a standard data format (similar to recipes) and get picked up by a massive meeting indexer. But then I realized that event coordinators want a lot of control over RSVPs, sending messages to attendees, and the ability to collect money ahead of time to pre-pay for event supplies, etc. It really is annoying that you need a platform to handle this, but anything else might end up being too complicated.
