Ad-annoyed
Well, judging by the amount of spam adverts sponsored tweets that started filling up my Twitter timeline over the past few months, Twitter are already well on their way to transforming themselves into the latest "ad-slinging" social network.
After a few weeks of replying to the companies foisting the spam adverts sponsored tweets upon me, asking them questions about fictiious health scares with their products, I eventually gave up and closed all my Twitter accounts.
Any other 'despisers-of-spamverts' wanting to flee Twitter before it becomes intolerable should check out the ad-free alternative app.net. Although in theory it's a paid service [hence the lack of ads], it's pretty easy to score an invitation for a free account, with a bit of judicious Googling DDGing. The clientele seem a bit more "tecchie" on ADN [as its aficionados call it] too.
