Did you know that you can actually be paid to tweet? I use sponsored tweets and I get paid in paypal to tweet a short message for advertisers.
It's easy to sign up and you will only get emails when you have a tweeting opportunity available or when you make money.
Disclosure: This is not a sponsored post, however I have a referral link posted and I may make a small fee paid by sponsored tweets if anyone chooses to sign up under me. The opinions are my own.
