Twitter users with large followings, such as actor Ashton Kutcher or CNN, can start earning money from posting content on the micro-blogging site after a UK technology company launched a subscription service called Super Chirp.

According to a report from Brand Republic, Super Chirp, created by software firm 83 Degrees, allows any Twitter user to earn revenue through direct messages – the site’s private message system.

Users can set up a Pay-Pal-based subscription to their account through the Super Chirp site, setting a price of between $0.99 and $9.99 per month. Direct messages that they upload onto the site are then sent exclusively to all of their subscribers, who then receive the direct messages or ‘chirps’ in their Twitter account.

A similar service called TwitPub already exists, however it makes publishers create a new subscription-based Twitter account, whereas Super Chirp does not.

The software firm said on its blog that its hope is that the program will provide a means for people to quickly and easily enable pay-for information channels.

“These could be celebrity news updates, real-time data, or charitable micro-giving. Internally, we are calling them ‘paid streams’ – if you have something to say that others might find valuable, then Super Chirp can let you try out your business premise,” said the blog post.

The software firm is said to take a 30% cut from each subscription, part of which goes to PayPal to fees. The publisher of the content receives 70% of the earnings.
