Starting on November 1, Twitter began posting ads on individual users’ Twitter streams. While Promotional Tweets at the topf of searches have been available, the new Twitter stream ad would appear in a user’s Twitter stream regardless of whether they follow that advertiser or search for anything on Twitter. Ads will be places based on who the users follower (both people and products). Initially, these ads will be rolled out only to those users of HootSuite.
What do you think? Do you see the ads as an invasion?
