Working amidst the networking opportunities

We had a day full of networking opportunities and meetings at InSights today. I overheard a conversation from a woman who was wondering when she would have time to get any work done. Interesting question, considering I have the same dilemma. So, here we are late at night and I am writing a blog post, twittering, and updating my facebook account. Where does the balance come in to the in person social activites that are so important for growing our contact spheres? Does anyone have any advice on their strategy and how to keep it all simple?
