twtAd is a relatively new site that pays you to tweet ads on Twitter. You need to have at least 25 followers to tweet the ads for twtAd. Yesterday it was 50 followers you needed but they have changed it to 25 to make it more accessible to everyone. Also you should only tweet the ads every couple days or not more than once a day to keep your Twitter account in good standing. You don't want to be accused of spamming. Although you can tweet the ads up to 3 times a day.
It's easy to tweet ads, you just find the one you'd like to tweet and click the link where it says "click here to tweet". You can also use more than one Twitter profile to publish ads through twtAd.
