The title is shorthand for asking: "What online photo sharing site do you recommend... and why?" I titled it as I did because, in looking around at many posts, it appears that the most popular answer might be "Flickr". So, if that's the answer, I'm just curious as to what reasons might lead one to choose it (over, say, Photobucket, Webshots, or dotPhoto).
Or, if something else, what and why?
So, please share your opinions on this, and on any other factors I should take into consideration.
PS Hopefully I chose the right forum: I also considered the "software" forum and the "(online) printing" forum.
