I've used photobucket but that was mostly for eBay auctions - linking additional pictures so I didn't have to pay more in fees.
I never bothered to organize it nicely since it was just my "workspace."
And I noticed on their blog that they're in the process of testing a beta revamp - so who knows how that will end up.
Flickr is only $25/year (to view more than of the most 200 recent pics) -which is fine - but I've never been crazy about the interface.
I'm guessing all those sites are all moving in the same direction - assuming that users are trying to/want to consolidate their photos, currently located on multiple sites and devices - and want to share them with the world.
Not me.
I'll deal with the next week.
