"The real-time web," writes Georgiana Cohen , "is about immediacy, availability, presence and on-demand engagement. It's about a pulse of information that we have no choice but to feel for, a stream of content we have no option but to wade into. It's not just Twitter, though that's the most prominent example. It's seeping into every corner of the online world." One really good example of that are the real-time online events, which are beginning to proliferate. But also we are seeing real-time publishing and real-time data and information. But "the tradeoff is time. You have to be there, and being there takes time."
