Bonus - livechat from livefeed is possible now. It was a result of livefeed updating (Stuffman said he deleted and refreshed the livefeed chunks, meaning the game will have to re-process them).
EDIT: For now, when chatting on livefeed your IP address will be visible to all using the livefeed, and maybe main game too. I've told Stuffman to mask them in a similar fashion to what DDR did on the old server (eg. web-001, web-002, etc.), but not how to do so (I don't know how to do that).
IPs are now masked, no need to fret about that now. Chat away! (though I think the 5-second cooldown is still there to block spam)
Chunks are also updating slowly...it seems to help to explore again. I just hope it doesn't end up corrupting the entire thing unlike what happened on DDR's server where post-1.7 the livefeed was borked and was only useful for relative player locations.
