Is this a free service, taking donations or do you plan on charging at some point?
Regarding monetization, right now my goal is to make this as useful and attractive as possible to people. Down the road I'd really like a donations/pwyw approach. For me travel and generosity go hand in hand, so I think it would be meaningful. Not sure if it would work, but I'd be willing to give it a try.
Signing up and playing around a bit is on my todo list for the end of the week. A couple questions. Do the locations have any function or are they just for reading? Are the albums shared by default?
Have you considered a way to let a couple people add to a single trip album? I find that coordinating pictures after a trip can be a challenge, from receiving a zipped dump of all pictures to just getting 1 or 2 by text. If I went on a weekend bike trip with 3 friends it would be kind of nice to let them put a few pictures in and have a semi collaborative album. This might be going too far from your goal, but it's been an idea I've been thinking about as I stopped using instagram for sharing trip pictures with friends on those trips.
The "MVP" for collaborative albums would be sharing an account. At this point you could even create a new account just for the trip, so your friends don't get access to your other photos. I realize it's not ideal, but maybe it's enough to try it out?
The albums are shared insofar as anyone with the link can see them and they get indexed by google. But there is no central feed where albums or photos might appear. Adding password protection and a noindex option on a per-album basis is also on my list.
Don't know why I didn't think to do that, I'll try to convince a friend or two to give it a test.
Would be great if you could spread the word, thanks!
