I observed the same segmentized silos problem a little while ago. Initial reach is SOOOO much harder when federation doesn’t work.
Reach is there only when some popular tech vblogger appears, like The Linux Experiment on TILvids - and that’s it. Most people are there for that channel and that channel only (Nick’s done a good job at promoting it, as we see), which must mean the impression other parts leave on a viewer is considerably worse.
