I met Petri Kainulainen at Engineer in Marketing meetup in Helsinki. Petri gave a great presentation with valuable content for anyone who writes a blog or aspires to write one. I thought I could help people to find Petri´s great presentation by making the story a bit more visual. So I gave Petri´s slides a little makeover. You can find Petris blog at http://www.petrikainulainen.net/. If you want me to do something similar for your story, you can contact me at timo@havain.fi or +358400407611
