What is most beneficial for an individual may depend on their primary focus. Since I am a Broker, the whole conference interests me.
I currently do not have a blog.....under consideration at this time.
To answer your question though... I was mainly interested in talking to other attendees about their social media strategies and had some great conversations during the pre-event meet ups and the conference. I did get a chance to check out the Trulia breakout session on building online referral sources and was glad to find that many of their tips resonated with my thoughts on the subject.
A next generation agent looking to stay ahead of the curve should definitely put the Inman Connect conferences at the top of their list of events to attend.
