If you’ve always wondered if Twitter was a passing fad, here’s something to make you think again.
Dell is using Twitter to announce limiter Twitter-only discounts for those who subscribe to their tweets.

It’s from the Dell Outlet Twitter account. The price for these refurbished items have an expiration, a bit like an eBay auction. The URL takes you to a micro-site with a ‘Special Twitter Offer.’ It encourages you to Add Dell Outlet as a Twitter friend.

As many predicted, the gap between a new web 2.0 application, and the creative uses of it, has shrunk like heck.

Could ROT (Return on Tweets) become a measurement tool?
