I attended minicamp last year, and I followed up with almost all of the attendees since then. I have had periodic Skype chats to see how it impacted their lives, so I can pretty confidently say that the minicamp:
Had a dramatic positive impact on some people
Had a significant (noticeable) positive impact on almost everyone
Had no noticeable negative effects on anyone
It definitely had a positive impact on me, but I represent more of a median result than an outlier. Since minicamp, I:
Sold my company, and am on track to make more money in the time since minicamp than I’ve made in the past few years. The decisions that lead to this were a direct result of the systematic decision and planning process I implemented because of minicamp
Turned down a job offer at Google to work at an even more awesome company. I both learned about—and got an interview with—this company directly because of a contact from minicamp
Improved in a hundred small ways (again, directly attributable to notes I made at minicamp), from fashion (I now regularly get compliments where I got none before) to health (I use less time to exercise and eat, yet feel much better)
There were definitely parts of the minicamp that could have used improvement, but these were mostly a variety of details and logistical mistakes that will go away with practice on the part of the organizers.
If you’re even thinking about this at all, you should apply. The cost is HUGELY outweighed by the benefits. I’ve probably gotten a 10x ROI (assuming I had paid the amount listed here and including the value of the time), and it hasn’t even been a year....
I’m happy to answer any questions about my experience (or my observations of others’ experiences).
Not to be annoying (as I often have questions like this as well), but I’ve found that Google is remarkably helpful in answering those questions. In fact, I tried two of the example questions and the answers seemed very reasonable to me:
http://www.google.com/search?q=how+to+deposit+a+check
http://www.google.com/search?q=how+to+buy+stocks
I also use Google’s suggestions (ie, by typing into Google Instant or Firefox search bar) to help phrase my question in the most common way, or to provide alternative related questions that might be more what I mean. For example, when typing “how to buy stocks” it suggested:
“how to buy stocks with out a broker”
“how to buy stocks online”
“how to buy stocks for beginners”
