You can use linkedin for all sorts of things. To learn and share, to build a following, to promote your business, or just to practice using the infinitive form of verbs.
But for me the best thing is connecting with interesting people and building relationships in the real world. With that in mind, it was a real pleasure to meet Jacob Holst Mouritzen in Copenhagen last night for some great food, drink and conversation.
I highly recommend connecting with him if you're interested in evidence-based marketing, or looking to build your network in this part of the world. He's a bon oeuf, as they don't say in France.
