Hello Pertti, Polling once a minute is quite slow, actually. You don't need the channel API for updates that are infrequent as once/minute.The Channel API is meant for realtime communications (i.e. seconds/less-than-second difference between messages) - for example, if you were implementing a chat app.
Essentially, if you want to push updates in less than a handful of seconds, use the channel API. For anything else, AJAX/JSONP pull updating is completely fine. ----------------- -Vinny P Technology & Media Advisor Chicago, IL My Go side project: http://invalidmail.com/ On Saturday, May 4, 2013 11:32:48 AM UTC-5, Pertti Kellomäki wrote: > > Hi all, > > I am building an app where users can post comments and the like, which > should be pushed to selected other users in near real time.
