Ellie K writes "While not quite as bad as it sounds, Twitter will soon be identifying followers with certain interests based on the content of their Twitter usage, and then providing this info to advertisers. Twitter is already selling sponsored Tweets for $100K or more. These reader comments captured the disquieting feeling I have: 'Twitter selling followers? Will that be the same as Google selling top position in SERP?' and 'I wonder when Facebook will start to sell friends.' Advertisers will be allowed to purchase placement in lists of 'who to follow' recommendations targeted to users with particular interests on Twitter."
