Here's an interesting article about universities on Twitter in the Times today.
You (Student Development staff) probably know that Student Development has a Twitter presence (http://twitter.com/uolsd) which we're only experimenting with but already have 129 followers. We plan to get helpdesk staff to be active on the account on our behalf using either Hootsuite or CoTweet. We'll also be sending out news tweets on a regular basis in an automated fashion using FutureTweet (or maybe we should just link the RSS news items to TwitterFeed?). Let me know what you think.
