Picassa, Flickr mashups, etc., are great for people who love to mess with photos. But if you don't, the whole thing leaves you cold. I'm in the later category. Although I love maps (pam spelled backward is map) and think the mappr idea neat, I couldn't use it because it was down the day I was working on this project.
So while I appreciate the technology, I would not use it, unless it were for a specific work application. The software looks fairly straight forward but I am sure there are "goobles", that people run into that would require working through.
