That sounds weird. There should only be "TV Tuesday", which is what I see in browser. I pin the daily thread when I get up in the morning (between 5 and 6am usually) and unpin yesterday's thread at the same time.

As @thegiddystitcher said, there seems to be a lot of federation / replication issues between instances. I've spun up my own instance yesterday to play and I can't see most of the threads / comments on here, even the stuff created after the instance started.

We're on v 0.18 of Lemmy, so we're still in alpha / beta stages and the two creators are currently victims of their own success - I'm sure it'll settle down and start to work given time. We just need to keep momentum (and faith) and not give up on the platform.
