I highly suggest spacing out your promotion posts. When you do 3-4 in a row, it decreases the likelihood that earlier ones in the day will be investigated. The queue option would be ideal for this.
We do space them out by about 30 minutes each, the reason we don’t space them out further is that we don’t have a filled up queue and the three posts are usually prepared on the day they are posted, if they’re spaced out more and we miss the queue time for one it’ll only post two and then one a day after, which is kind of inconvenient. Our posts get about the same amount of notes each time and we did a survey for the busiest times on tumblr each day, so I don’t think it poses a huge problem ^^
A herd of buffalo can only move as fast as the slowest buffalo. And when the herd is hunted, it is the slowest and weakest ones at the back that are killed first. This natural selection is good for the herd as a whole, because the general speed and health of the whole group keeps improving by the regular killing of the weakest members. In much the same way, the human brain can only operate as fast as the slowest brain cells. As such, when reading Ask Pun kills a brain cell, you get smarter!
Good, because I think I just lost a few trying to comprehend that…
