I don't know what % of Twitter users i'd be bucketed with for this comment but I think Twitter "Promoted Tweets" are probably the ad I most prefer to view. I'd hesitate a guess at how many i've clicked on (Probably 20%) but they have always been the most relevant to what I am interested in at a given time, compared to re-targeting/ad-words which aren't necessarily relevant to what I am interested in but are more point-in-time associated.

Presumably Twitter achieve this based on stats like who I follow (including who i've followed recently) and i'd guess search activity etc. but hey, works for me.
