I finally went pro on flickr yesterday. Spent 5 hrs recreating all the sets I had to delete because of the 3 set restriction in normal flickr account. Creation of a flash badge showing my photos was the best part of it. It looks cool on my blog.
Today morning, to my delight, found Flickr's interface revamped. The front page now accomodates 2 photos in a row, and the sets are all moved on to the right. Organize now has tabbed browsing which allows editing of multiple sets together. Secondly, it also allows batch editing of randomly chosen photos. All the photos are by default shown in a horizontal bar located at the bottom. A mouse-over shows the date on which the photo was uploaded. While dragging photos to do batch editing, a nice message pops up on the top right side, with a cool fading effect. To remove the photo, just drag it back to the bar, which automatically fades to act like a trash.
There are links on the top, which provide access to any functionality within 2 clicks. The coolest thing I found was Explore->Calendar, which shows the month with the most interesting photos uploaded on that date. End result is an awesome calendar; which I'd surely like to buy if they put it on sale!
There is a lot interesting stuff in the new interface. Conclusion, I found the new interface to be much more usable; and obv. has more eye-candies ;). In all, flickr is utilizing AJAX to its max limits; and becoming unbeatable as an online photo sharing service.
