My wife and I were planning a trip over the holidays and it was getting out of hand on Google Docs.
Ended up building a small tool over 3 days (v1) and then sharing it to Reddit on day 7. Got a bit of traction and started working on it full time over the summer, but I don't think I can figure out a business model.
So enjoy an ad-free, complelety free collaborative trip planning and travel blogging tool for obsessive planners!
