Canadian public relations practitioner Dave Fleet says Twitter has moved through the Gartner Hype Cycle. It is now at the point where it could quickly become unfashionable. In his  Five Potential Effects Of Twitter’s Shift To The Trough Of Disillusionment.  Fleet charts the technology’s progress and predicts what will happen next.

At first sight, Fleet’s analysis seems to be on the money. But there’s something else going on with Twitter. After a period of stability, the service is changing. Earlier this week the company altered the way users propagate messages. This changes the process known as retweeting.

In other words, Twitter is still evolving. It will probably be a different beast by the time it resumes its progress through the later stages of the Gartner Hype Cycle. Or maybe something else will replace it.
