How are url shorteners making money?
mikeyur: They don't. To be honest the majority of url shorteners don't make any money at all. I know because I run one. http://urli.caIt costs me nothing to run because it uses next to no resources on a server that I already pay for and I got the domain for free.//Sidenote, if anyone is interested in using the service, we have a really simple api (as all the services do) http://urli.ca/api note: the urls auto-increment (ie. ab/ac/ad/ etc.)
