Some of the Things I Love About Flickr:

Saving my favorite photos of others (see photo for a preview of my favorites)
RSS Feeds (right click here for the feed to my photos) for photos and comments
Buddy Icons
Testimonials (I only have one, feel free to write one for me here)
Contacts
All Sizes, you can see the original size of the photo as it was uploaded
Tags
Photosets
Free and pay accounts and easy to set up your new account
Can sort by date taken or date uploaded
Easy name and description editing
The ability to link photos to your blog with ease

However, it is still in Beta, and a few things that are promised, including one that I will love, to be able to customize your home page so you can show the photos and photosets you want.

I still love PBase, but Flickr is more fun for personal photos and photos of my creations. 

Oh, and please post a photo of your purse and it's contents!
