I love this little feature of Flickr: You can edit the title and description of your photos without reloading the page at all. Just click the title, edit it in the form widget that shows up, and when you hit SAVE, it does a request to the server in the background to save your new title. Very smooth.

Even better is the way they draw your attention to this feature: When you mouse over the title or description of one of your own photos, the background color is highlighted in a light yellow, alerting you that something’s up.

But, even better, the yellow color stays for about a second or two after you’ve left the title. This is what clued me in to the fact that it’s not just the usual :hover effect, something special is up here.

To make things complete unambigious, they also say in italics “click here to add a description” when you haven’t yet, and they have a tooltip that says “click to edit” (which, btw, doesn’t show up when the “click here to add …” text is already showing).

All in all, a simple and brilliant piece of work. Kudos.
