Just realized I have been blogging about Java, web and related technologies for 13 years now... since 2006 ! ... more than 950 articles has come out of that. I hope I have 13 more years of serving the developer community in me ;-) #Java

This saturday my developer tutorial website tutorials.jenkov.com crossed 100.000.000 page views in its life time! I guess I can call myself a blogger now ;-) Thanks to everyone who've visited my website over the years and helped reach the 100 million page view milestone :-)
