When tech guru Robert Scoble says something’s hot, you can bet that it is. And guess what? He’s as hot as hell on Twitter. On this video, Scoble explains in detail how businesses can hit home runs galore through the use of this micro-blogging service. Scoble also discusses Jaiku and Pownce, the big competitors for Twitter. He claims that Pownce has the better user interface and some cool features, and points out that these services enable threaded discussions. In answer to the question about Twitter’s lead, Scoble suggests that Pownce is pulling in big numbers of users – and fast. He suggests that these platforms won’t be mainstream for another couple of years and all of the platforms struggle for the attention of consumers. He suggests that companies such as Twitter are cheap to build and run and are not as exposed to the problems of the tech bubble that we saw in 2000.
