@alyx Agree, completely. Never understood why birdsite chose to divide our interactions in ways that made following back through time an impossible set of swaps.

If masto could give us a sequentialised tree as our TL (will need an arbitrary or specifiable depth*n of related accounts, difficult SQL, not impossible) then we'd be very, very happy.

Just went away for a dig and mulled on the idea, the data structure would have to be heavily normalised, which it doesn't look like from a cursory pass through.

Damnation. The overhead would probably be too intense for reasonable performance with the existing structure.
