Once WordPress had properly introduced and provided the necessary support for custom post types, I no longer needed to continue developing GeoPress as I was then able to bring the same functionality into both WordPress and the recently launched BuddyPress.
In it’s initial release, it provided integrated FourSquare support, which was eventually removed and made available as an additional module that was not part of gPress core.
gPress was also the first “geo” specific plugin for BuddyPress.
