I guess we need to look for the buzzword "push" rather than "realtime" now-a-days. At least, that's closer to how I use "realtime", rather than 5 minutes mechanical polling.

"Sure, realtime-nazi, but what would you suggest?"

Personally I feel up to 30 seconds is acceptable, but I rely more on the underlying method of delivery (push/long poll for change vs. polling and comparing for change). In close comparison to the definition here: https://en.wikipedia.org/wiki/Real-time_web

> receive information as soon as it is published by its authors, rather than requiring that they or their software check a source periodically

For a consensus, see http://stackoverflow.com/tags/real-time/info and/or http://stackoverflow.com/a/5286985

Or am I wrong? What is a better label for what wikipedia defines as realtime-web?
