People keep saying that the Alexa and Klout metrics are worthless. From a purely scientific point of view, they have a point: the algorithms to calculate the world-wide ranking of your site or your world-wide influence are bound to be suboptimal. It's madness to think that you can 'measure' something like 'influence'. Yet that doesn't mean the metrics are worthless! Let's see how I use Alexa and Klout:

I predicted that August would be better than July. I was right regarding sales; I was wrong regarding the web statistics:

Ja, ik heb deelgenomen aan iBoot, en ik vond dat een schitterend initiatief. Ja, ik heb deelgenomen aan FTF-F, en ik vond dat tegenvallen. Wat was het verschil? Dat vond ik onlangs goed verwoord terug in De Standaard, in de column van Dominique Deckmyn:

Looking at the ranking of itextpdf.com, I think the summer vacation is over for most developers:
