Amen to that Donal,
Everytime I would go to a "new" event, my wife would ask. How do you know these people are who they say they are. I say trust me, I've seen pictures....they aren't exactly the bruiser types!! 
Kalen:
That is spot on. My wife thinks I am nuts. She keeps saying "you met this guy on the internet?? you have plenty of friends, why do you need to make friends on the internet?" She thinks that I am a total nerd for my "golf course" books and other stuff. So according to my wife, this is a redundant thread, as our mere involvement on the site qualifies. I just tell her "till death do us part" so you better get used to it.
In answer to your question, here are some signs where I realized that I had "jumped the shark":
1. You find yourself saving things like pencils, matches and shoe horns from courses that you have played. Honestly, what I am going to do with this stuff.
2. You have (1) an Excel spreadsheet of over 500 golf courses in the US that include links to all articles on the internet concerning the course, the architect, year opened, city and state and where it could fall in a trip (ie. Sawgrass is more likely to be included in a Sea Island trip, than any Florida trip), and (2) photo files on every great course that you have played with tee, fairway and green shots.
3. You know who Ann Liguori is because she hosts a charity outing at Maidstone every year.
