I think the next big thing to hit buddypress would be a significant googlemap geo-location based plugin. There have been one or two plugins which have popped up, but none that appear to be in good working order for use on WPMS/BuddyPress latest install (3.01 and 22.214.171.124 respectively at time of writing).
Are there any thoughts for developing maps to show member locations, group location and geotagging posts, blogs etc?
Or are there any working alternatives out there?
For a visually based, interactive social network, I think geo-location and member mapping are an important aspect for BuddyPress
