Real-time web defined

Real-time web: According to Ton Zijlstra:

Real time is when you get your data stream through the web the instant the data is generated. Examples would be microblogging tools like Jaiku and Twitter, photo upload sites (Flickr, 23, Twitpic), live video (Qik, Seesmic), but also things like SMS (Treasuremytext.com). Another example would be the number of mobile phones and their speed of movement on highways, such as TomTom uses to show you traffic congestion in their route navigation software.
