How I hate it when I'm clicking something on the federated timeline to have a closer look, but at the same time the timeline updates and I open a different post than intended. Then I go back, only to see that the federated timeline has now completely different content and the interesting post is nowhere to be seen any more.
Federated timeline just works too haphazardly.
