It’s really unfortunate that Lemmy handles deleted posts in this way. It’s one of very few genuine advantages of the Reddit platform. Over there, if the OP deleted the post, the text they wrote would no longer be visible, but all the comments under it still would be. And people could continue to have that discussion, so long as they had the link.
I went on a long run on the 1st September. First day of Spring down here in the southern hemisphere. Basically still winter. And it was 32 °C by the time I finished at 10 am. Over 30. In the morning. Just one day after winter. Wtf.
