Freedom of speech is the first amendment of any U.S citizen, the question is would you pay to post yours? There has been rumors circulating the Twittersphere about the company charging a small annual fee. Personally I wouldn't mind paying $24/year for the service, I think it would cut back on a lot of trolls and get it back on track for what the main purpose was...NETWORKING.
I can also see the other side of the coin where we've been given this app for so long that paying for it might not seem fair. My solution to this problem would be for them to make a Twitter PRO version for users that are willing to spend that extra money per year. Twitter PRO could have tons of customizable features and it wouldn't alienate the regular Twitter users. Let us know what you think of this idea and if you'd be willing to pay for Twitter!
