URLShortener

Hey. All the cool news sites have their own fancy URL shorteners (and some like BBC are just cool and have a short URL period.) Toss your ideas in here

Ideas:

• Can only link to SoylentNews.org pages (maybe a few other select URLs?)
• /a/ARTICLE_ID url links to the article on SN
• /u/USER_ID_OR_NAME links to the user on SN
• /RANDOM_ALPHANUM works like a normal URL shortener, an arbitrary URL in the soylentnews.org domain
• an interesting comment on Soylentnews with ideas about article and comment URL format
