Choice of fonts is really important when you write some posts on your blogs. I have found on Standard Web Blog a statistic scheme which shows to you the 5 most used fonts on Weblogs. As you can see, Verdana has a good success. In fact, it is not a surprise because I like this font for web pages.
However, I’m surprised to notice Helvetica is missing in this top 5. As for me, this is a good font, really useful and clean for titles. For example, we are using it on Dowego.fr on the right side.
