After sign in, if I do some activity on the current page. E.g if I accept an answer, then as per the rule my reputation should increase by 2 and it increases also but the updated reputation is not showing immediately. To see the updated reputation I have to refresh the page again.
This kind of situation also happens when some new data is coming to my inbox.
Isn't it possible to implement push technology to immediately show the updated things. If it is possible, then why stackoverflow doesn't implement it?
