Melissa Chang at the Industry Standard leads with a series of suggestions on how she believes Twitter could make money (and make it quickly). In the last year Twitter has emerged as a popular mini-blogging device allowing users to update their status, among other things, 140 characters at a time. With user count estimated at roughly 2 million, Chang highlights everything from advertising to a subscription model as potential sources of revenue generation.

Here are her top 10 suggestions:

1. Banner Advertising
2. Paid Posts
3. Sponsorships
4. Charge for ad-free usage
5. Tiered subscription model (free for everyone but charge for special features like photos, etc.)
6. Offer a monitoring package for businesses (to track their brand identity within Twitter)
7. Charge companies that use the Twitter API
8. Affiliate program (pay users if another use buys a service/good based off of your reccomendation)
9. List rental
10. Mobile payments

The subscription models seem dubious and at least one suggestion, affiliate marketing, seems to compromise the integrity of the social network. The most creative suggestion is mobile payments.  Chang, assuming the mobile payment market is set to explode (which it is), makes the argument that it will require a site which already has some kind of user network for mobile to succesfully integrate.  Additionally, Chang sees powerful synergies from sharing data tracked by mobile consumer behaviour and the kind of data and information submitted to Twitter on a regular basis.  Read her full article here.
