I will be spending more time with my family, and less time at the computer over the coming weeks, so blog posting will be irregular and unpredictable. Going straight against the rules of good social media behaviour, I do not build up an article bank and auto post new posts at the optimal time for maximum impressions. Most of my posts are spontaneous and written "live". I hope all of you have a good summer.
