When should I be posting s**t?

SumAll did a bunch of research around when you should be posting stuff if you actually give a s**t about people reading your tweets/posts/whatevers, and came up with the following data.  Mind you, they don't actually say so, but I assume that they are referring to the timezone of the target audience :-)

Anyhow, this is the worst possible time to post stuff :

And, these, conversely, are when people are paying attention..

Finally, these are the best times to "optimze" your "social media interactions" (yeah, i just threw up in my mouth)
