You open Twitter and see a notification at the top of the screen telling there are new tweets, click here to show them. You hesitate just long enough that once you finally are about to click it the notification disappears. Great, now you have just liked some random tweet.
The so called user experience and design has produced some really annoying things. The one I'm annoyed almost daily are those disappearing notifications that prompt you to click on them but just as you are clicking one it disappears and you end up clicking something else.
Who thought that it would be a good idea to lure user to try and race the timer trying to click the target on time without even giving an indicator of hoe much time we have left? That timer would be the minimum that these elements should be required to have.
Even better would be if they didn't disappear on their own at all. Just keep them there on the screen until the user does something else. The explicit action of doing that would be a strong cue of user not being interested in the action of the popup. Just don't move the page when doing so if the notification is actually a part of the flow instead of popup. That's even more annoying as in addition to false clicks it causes unnecessary movement on the screen.
