Definitely! I consider myself somewhat of a novice and went last year for the first time and came back with pages and pages of good, actionable information that I could apply to my sites. Once I did I saw noticeable improvements across a wide variety of areas covered in Mozcon - local SEO, social, link building, etc. Will be in attendance again this year.
The insight that I gained in session and in talking with other attendees was invaluable.
