When I first stumbled upon “StumbleUpon” about two years ago or so, I was fascinated by the idea of this application using “collaborative filtering” – the wisdom of the crowd. But after a while more and more friends were using del.icio.us, which wasn´t that brilliant at all to my opinion but simply more often used. Most of all I am missing a function which helps you to identify new interesting websites by simply clicking on one button. Moreover delicious doesn´t help to identify “Friends with same interests” like for example Facebook offers with music taste etc.
Now, a year after del.icio.us had its tremendous boom StumbleUpon seems to catch up.
Sometimes websites have strange “careers”: it´s a bit the word of mouth, a bit – of course – media which helps to boost websites, and finally with a little help from one of the big Web 2.0 companies (in this case Ebay´s US$75Mio.) you can do it!
