I just used this spreadsheet to project the ad revenue from my content websites. I learned that generating more traffic is much more valuable to me than increasing ad clicks or even the price I charge for my ads. Nice tool!
Sounds great to me. I'd love to go. I would enjoy the change of pace and meeting some new people (who are hopefully working on interesting projects). Fast/reliable internet is a MUST. There are plenty of beautiful/relaxing places in the world with fast internet. I won't expect to get as much work done as I usually do. It would be nice if there were some side trips planned during the afternoons/evenings.
