Its not about duplicate photos - almost every photo manager can do that. But consider this - I've got over 25000 unique photos, never really been looked at or sorted. Nothing ever deleted. I could use Picasa to go through them individually and tag/upload/share the good ones, but I'd have to remember where I was up to. I could set up tags Good & Bad and tag them all like that and if Picasa could show me all the untagged photos that would help. What PhotoSorter does is simply this - step through each photo one at a time and flag it as a keeper or not. You can exit and resume from where you left of at any time, and export the flagged photos at any time. So I'm using it as a convenient way to reduce my crazy photo collection to one that is worthy of loading in Picasa and manage/share there.
