I think General discussion has a place on giffgaff.
The community has all the serious forums for those that want that.
Help and support.
So it's nice to have a board for general discussion. Granted the board does have some trivial posts, but we don't have to contribute, just scroll past.
Debate on GD has changed in the time I've been on giffgaff. It has lost the 'bite' it had and the sillier posts seem to get the replies, but that's how the majority seem to like it.
