Yep, I can sign under almost all You said, good stuff! Only thing I started to think about and have different opinion is using the bid bots to rise the value of our posts - of course, it can be difficult to understand for beginners how it works, what is worth doing and what not, it is high risk, that instead of faster grow and develop we will loose our money to the bots... but the other side of the coin is that proper using of such option really speeds up the growing process and make our posts more visible to people - our potential followers. It helps but as I said - not always.
The only rule here should be - don't try to push up shitty content! Always remember to give Your best and make it worth something to others.
