Needs something that resolves case-sensitivity in usernames. For example, because I've chosen "case_sensitive" as my user name, no one else may choose "Case_Sensitive" or "CaSe_SeNsItIvE" et c. Meanwhile, a request for "Case_sensitive" will fail. http://social.gnod.com/hn:case_sensitive http://social.gnod.com/hn:case_sensitive! http://social.gnod.com/hn:Case_sensitive http://social.gnod.com/hn:Case_sensitive! It would be possible to fix this by crawling and scraping an enumeration of all valid user names into a lookup table, and then matching a query tranformed to all uppercase (or all lowercase) letters against the similarly transformed lookup table which retains the valid case sensitive version, then showing the results with the corrected name.
