Short URLs

Flickr provides a URL shortening service for uploaded photos (and videos). Short URLs can be useful in a variety of contexts including: email, on business cards, IM, text messages, or short status updates.

Every photo on Flickr has a mathematically calculated short URL of the form:

http://flic.kr/p/{base58-photo-id}

知らなかった。
昔ドメイン取れなくてeを抜いたのがちょうど良かったね。
でも個人的にはflc.krの方が好きかな？
