it is the cause of every single unpopular decision around tag search/visibility we have had to make, and the cause of all performance issues that stemmed from those decisions. i will not elaborate on this further. i hate the cohost global feed and spend much of my time considering ways to render it fully useless since the only way to truly kill it is through irrelevance.
EDIT: i'm elaborating a bit. the performance issues don't come from having a bunch of posts in the same tag (this costs us literally nothing), it comes from the arcane "effective search tags" system we had to create to cut down on the community/social issues that stemmed from people using the global feed to put posts in front of a much larger audience than was initially intended by OP, which was almost exclusively used for harassment. most of these perf issues have been resolved by now but it sucked to get here, and (at least imo) the global feed phenomenon has stunted the growth of a healthy tag culture.
9AM EDIT: i am locking comments on this post because it became mad unconstructive overnight. the correct read of "render it fully useless" is "make it so that it's not necessary", not "force everyone off of it."
