Hackaday used to give a good boost in views, but now seems to hardly make a blip.
Maybe it doesn't for you big whales, but for the us little fishes it can increase the view count by three orders of magnitude. 
What I meant is that I think the view count has dropped a lot from Hackday. So it's not that fact I don't see it because my channel is bigger now.
I've looked at the actual hits from Hackaday after I get linked there and it's pretty small, like in the hundreds. IIRC It used to in the many thousands, like 10 times more than now.
So perhaps their audience has dropped, or maybe there is more content on their channel so people don't watch them all, or maybe the majority are already subscribed, or a combination. But I suspect it's not what it once was.
