As someone who runs another photo sharing site that organizes for you by date, I can say yes.
First, it's important to know that uploading a thousand photos is way easier on such a site, since you do no organizing work. Try uploading a thousand photos to Flickr without culling, organizing into albums, tagging and captioning, and see what your result looks like. It doesn't have to be like that.
Second, they have to be your photos for you to appreciate chronological organization. When I look at my own, I can say, "Wow, I just click 2005, then December and I see my Puerto Rico pictures. And I didn't have to organize them myself." You don't get the same effect looking at someone else's.
