The real-time web: RSS Cloud and Google’s PubSubHubbub
It was quite a revolution when RSS became popular (created in 1999, it became wide used around 2005/2006) and integrated in almost all tools. To the point that some people were even challenging that it would use too much bandwidth… Why is that ? While RSS is a neat system to find out when something changes on a website it still requires from the client to poll the server. Bad designed client (that were not using correctly the HTTP protocol and its 304 status code) and the multiplication of tools (CMS, CRM and co.) would load servers and the network and eventually causing some problems. After a while we get it to work nicely but notifications still relies on the polling mechanism and its frequency. Good… but not enough for the real-time web. Real-time Web? one of the 5 futurs trends on the web (see also a list on ReadWriteWeb of the Top 50 Real-Time Web Companies).
