Peter Rock has asked some fair questions about Twitter on his blog.

I already use a blog and an RSS aggregator. Is adding Twitter as a tool to post and receive information going to enhance or burden my learning experience? Is it that I need to follow only those who use Twitter effectively to enhance my learning opportunities? If so, what is “effective” twittering and how does it differ from effective blogging? Is the energy required to add Twitter to my toolbox and follow Twitterers worth the payoff? Are really good ideas and resources found often enough on Twitter that never surface in blogs?

I sent a link to his post via Twitter and asked people to respond. Within a couple of hours, he received 23 posts, many of them very insightful.
