There are plenty of people who like the club, so either their experience has been different or they don't mind getting dropped/riding alone. The ride listing is fine. Their website is more complex than that of other bike clubs I've seen, with more options for displaying and filtering the rides on the schedule. I can't speak to how hard or easy it is to post a ride since I've never done it. They typically post the schedule for the entire month during the last couple of weeks of the prior month, and I think the individual ride leaders send the info to a ride coordinator (one per ride category) for a mass posting rather than each leader posting on their own.

I think the issue I have with them is one of culture. My impression is that all bike clubs or organizations that try to have group rides struggle to some degree with pace inflation and keeping riders together. But different groups have different approaches, cultures and expectations.
