My second regular column for Mediatel’s Newsline, this article is a classic case of a pub conversation sewing the seed of an idea. I really wanted to get across how powerful a communications tool Twitter is at the moment and the challenges it will face trying to make money, particular amongst younger users. It’s quite a good discipline trying to bring it in under 1,000 words as I can tend to ramble. The article ends with a reference to Babblesphere, the fictional social media satirised in this recent Doctor Who audio play. However it would seem that it isn’t fictional after all!
