Jesus, Tumblr. I really don’t see a difference between the VERY annoying ads you’re throwing on the dashboard and the very annoying Dancing Man Mortgage Payment ads, which is one step away form the early very annoying pop-up ads of the 90’s.
What bugs me is how that “sponsored Post” dollar-sign symbol appears on some sponsored Radar posts, and not others.
Here’s a recent Puma-relate radar post that was clearly marked with the symbol (it’s that dollar sign with the rays radiating out of it in the lower right-hand corner):

Yet the puma post pictured above has no “$” symbol, even though we already know that Puma is a Tumblr sponsor.
So why identify some of these obviously-paid-for Radar posts as “sponsored content,” and not others?
Tumblr needs to make a choice: Either clearly identify all sponsored content as advertising, or don’t. This current practice of sometimes identifying it and sometimes not is lame and pointless.
