Website Response Times An Article by Jakob Nielsen www.nngroup.com Users really care about speed in interaction design...A snappy user experience beats a glamorous one, for the simple reason that people engage more with a site when they can move freely and focus on the content instead of on their endless wait. 0.1 seconds gives the feeling of instantaneous response. This level of responsiveness is essential to support the feeling of direct manipulation. 1 second keeps the user's flow of thought seamless. 10 seconds keeps the user's attention. A 10-second delay will often make users leave a site immediately. uxperformanceinteraction
Fucking up the world City Hall by Rafael Moneo, Logroño, La Rioja, Spain. Alexander : At least my experience tells me, that when a group of different people set out to try and find out what is harmonious, what feels most comfortable in such and such a situation, their opinions about it will tend to converge, if they are mocking up full-scale, real stuff. Of course, if they're making sketches or throwing out ideas, they won't agree. But if you start making the real thing, one tends to reach agreement. My only concern is to produce that kind of harmony. The thing that strikes me about your friend's building – if I understood you correctly – is that somehow in some intentional way it is not harmonious. That is, Moneo intentionally wants to produce an effect of disharmony. Maybe even of incongruity. Eisenman: That is correct. Eisenman: I find that incomprehensible. I find it very irresponsible. I find it nutty. I feel sorry for the man. I also feel incredibly angry because he is fucking up the world.
