Parallel testing of clusters in their current implementation (zoom) and proposed implementation (fanning) will occur next week.
Let's make sure the interactions on the clustered pin style is tested with user testers.
We discussed this early on, and decided to keep it as is. But as I've been using it, my intuition is strongly to have a single tap do "something" that acts on the pin without changing the map, and then a double tap for the zoom in.
That the "something" shouldn't be a table view popover, which could get weird quick on phones. But maybe there is a specialized treatment that limits the list to like ~3 top items or a shrinky dink cell style?
Its shippable as is, but Id like to revisit before we do.
