Subscriber surge accelerating
+100.0K subs gained on Apr 10 — the highest single-week gain in this 6-point window. Likely driven by a high-performing video upload.
Views floor is very high
Even in "off" weeks, Mark Rober sustains 12–18M weekly views. This baseline is a strong moat — hard for competitors to match at scale.
