I can't remember the last time a promoted tweet was relevant for me. I am not going to buy Samsungs new super expensive phone, I am not going to be using mail-chimp.

So why do I keep seeing ads for crap I don't need and products I already know about, instead of new products that are useful that I can actually use? Maybe if ads were useful people would want to see them and so they wouldn't have to be annoying.
