Slightly related: try to sync an external calendar feed in iCalendar format (also used in CalDAV) with Google Calendar. Google Calendar will use random intervals to synchronize. Often taking more than 24 hours... which is, in most use cases, quite useless. Sync in the same way with Facebook's event feed (same format) and changes appear within minutes. This has been the case for years. Google Groups are full of questions about this. I don't want to demand anything from a free product (Google Calendar is very useful in many ways). But somehow some feedback about 'shortcomings' like these would be hugely appreciated.
