Upon reflection, chit-chat is maybe not my preferred option. Especially when ‘chat’ is a euphemism for a flea. As in riding ‘flat chat’, which means galloping fast while holding your body so close to your horse’s neck that the fleas get squashed between. And chat potatoes, which refers to spuds so small as to resemble fleas. Chit-chat means small talk. Very small talk. Not my preference. The DT does more than that.

Maybe ‘Daily Ramblings’???

Or just leave it as Daily Discussion Thread - which is accurate and not demeaning. And we’re all accustomed to it.
