Since the Digg migration, when was that, 2010?
Since Reddit's APIcalypse the content of that site has gone to the drain. It is very clear that power users are no longer posting quality content. I am much more amused by Lemmy than Reddit nowadays, though it's true that it has that new car smell and the communities will keep growing and reforming from the Reddit ashes.
I don't think Reddit will disappear, but it's not the same site it was two months ago, that's a fact.
Maybe cross pollination? Many people have geraniums in the area and the bees likely carry the pollen everywhere
I also heard as a child that if a red geranium petal falls on the soil of a white geranium it can tint their flowers. But that sounds like a urban legend to me!
