I realize that the notification is there on a hard page refresh, but I would like to avoid refreshing the page to see that I got an answer or comment.

1@Gaurav - some more information needed. What do you mean by Ajax notification?– Sachin ShanbhagMar 31, 2011 at 6:43

@Sachin : I need not to refresh the page to see I got any answer or comment or not.– GauravMar 31, 2011 at 6:46

@Gaurav - That feature is already available since it notifies you on top left corner of screen when you get any new answers or comments. ;)– Sachin ShanbhagMar 31, 2011 at 6:48

@Gaurav - Oh.. ok, got your point :)– Sachin ShanbhagMar 31, 2011 at 6:52

Sounds like comet/long-polling, which could potentially be very many persistent connections to the server.– hyperslugApr 4, 2011 at 13:20

1@hyperslug - there is already such polling (every 45 seconds I think) in every question page that alert the user when new answer is posted to the question, or when the question is closed or deleted. So having the polling do some extra work shouldn't really be big burden. :)– Shadow The Kid WizardApr 4, 2011 at 13:22

@Gaurav - do you mean "Ajaxify" the global inbox so it will suddenly come to life showing a number all by itself? This can be cool indeed.– Shadow The Kid WizardApr 4, 2011 at 13:24

@Shadow Wizard : yes.– GauravApr 4, 2011 at 13:25

The cost/benefit ratio on this is kind of out of whack.
While we could reduce it on question pages, those are the only ones with a regular poll going on; every other page would gain a new background poller (or long polling, or whatever*).
That's a lot of potential load for marginal gain.
We may revisit this if we find more compelling "polling everywhere" features, since we could piggy-back on those requests. But for now, this is status-declined.
*Fetching the number is cheap, the # of connections is the nasty bit w.r.t. scaling.
