While interacting with a website, how many times do you experience the mind-numbing request of pressing "OK" or "Cancel"?

We, at Wallwisher, hate the concept of this idea, of asking for user confirmation, when it’s simply not required. What is required is a notification, and there are other simpler ways of delivering them.

We like to use simple popup messages which fade away on their own, without the user having to click on "OK" or "Cancel". Let’s say in a chat room, the common rule is not to post more than 2 messages in a minute, to prevent spam, and allow fair distribution of contribution. If a user tries to post more than 2 messages, instead of popping up a dialog box informing the user of the rule, and asking him or her to press "OK", we would advise the use of simple fade away popup notifications.
