I realise that PM is in the process of revamping the Public Lab and forum generally. One thing I'd like to see is an area that would be considered "Off-topic" or more for socialising. Especially in times when there are few issues going on, it is enjoyable to post random thoughts - sometimes relevant to the cellular device world, other times relevant to prehistoric worlds - either way, it helps maintain community vibrance and cohesion.
Currently the "Discussions" board is the place for such musings, but it might help to make it more obvious with a name like "Social corner", "Off-topic", or something more clever...
