I dont know about others and I am also not a regular viewer of study vlogs, but I will share my state of mind while I;m watching them.
There was a phase when I was in a rut for a very long time ... This can happen many times during the phase of our preparation where we are just not in the zone of studying.. I have been preparing from home and don't go the library either. I realized that watching study vlogs in such phases nudge me to come out of that rut and encourage me to make a plan for myself, to start slowly and gradually coming back to my previous performance.
..Ofcourse I dont watch each and every vlog that is being posted but ...Again, this is what helps me ...I don't know what others think about them.
About study vlogs I will say that there was a time when study vlogs were really nice. Now what I see is they are just made for garnering views. There are 2-3 of them which have come into my notice, where sometimes they show its there last attempt and then show that they are preparing for their first attempt. Similarly some show they have cleared and then they are again giving exams and all.
The problem is not ki dhanda banaya hua hai rather yeh ki they start giving gyaan on this exam, jabki khud ek attempt diya nhin hai. Misleading people. But jab youtube pe itna mislead kr rhi rahe hai through funacademy and all, toh yeh 1-2 naye aajayegen toh usse kya hi.
SNLogs was really good. Sadly she is not active now. She was class apart from recent ones which have come up. Now it is more like family vlogging channels , rozi roti dikhate hai. And promotions krte hai funacademy ka.
Basically vlogging not for motivation but because woh unka dhanda hai :/
P.S I really want to name them taaki people become aware and unko faltu ke views na de but I am not sure. I think mentioning them here faltu ka unko limelight bhi dega.
There is one named tara's ...... and one with some very ajeeb name ep---vlogs. Complete bullshit!
