Yep, interesting data, graphs, charts and information in general. But if I'm honest, I would say that nobody "personally" would have to lose sleep trying to make "plans" about when the heck publish their content & own posts just based on all these specific stats.
Given that from a "personal" point of view, there are still a lot of crucial variables that will continue to influence the success of their posts in terms of being widely seen, well curated and well rewarded. Like by instance:
- The number of followers they have.
- The number and type of #tags they use on their posts.
- And the communities and tribes they choose to share their posts with, among many other things way beyond the day or time of the day they post. ;o)
