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
The signature It has long been understood that striving for originality as an end in itself is the mark of an inferior artist. The personal style of a good artist is never something that has been deliberately cultivated and forced but something that has appeared unsought as inevitably as the personal style of a man's handwriting. But since artists of note are seen to have a distinct personal style, no artist can hope to make a reputation in a competitive society unless he too can show a distinctive style which easily differentiates his work from that of other artists and draws attention to it. Therefore artists of little capability or uncertain vocation will take great care to make their work look 'different', whereas those with any certainty in them will know that their work cannot help but look different from that of other people any more than signatures can. It is worth reflecting that the fact of the unmistakable individuality of each man's signature is one foundation of modern commerce everywhere. To establish the individuality of it one need not write it vertically up the page in letters two inches high. And yet there are only twenty six letters, and everyone else uses them too.
