On most of my sites and blogs I write in Dutch. Since 2008 I have been visiting more and more international events. Also the number of international connections on my twitter account @ernohannink is 50/50 (English/non-English). I tweet in English and Dutch on the same account.
Meeting a lot of foreign people made me want to start an English site and blog. This site should also give me the opportunity to offer my services outside the Netherlands.
