The second speaker of the How To Web 2010 conference was Boštjan Špetič, the Zemanta CEO.

Boštjan’s presentation was entitled: “Measuring the blogosphere… or how big is it really?”. In his presentation Boštjan compared data regarding the blogosphere size obtained from different sources and highlighted the huge differences between these sources.

The bottom line of Boštjan’s presentation was that:

• The blogosphere is 3 to 5 times overestimated;
• It is very important to measure what you are working with as “If you can’t measure it, it doesn’t exist”.
