URL shorteners don't deliever the necessary stability anymore.This is why people decided to have their own service.

If one has a web server, the installation of such service is a piece of cake.

The only thing besides that is owning a short domain name that can provide your newly created address a short URL.

More than this: people are afraid of spam, malware, not knowing where the redirected link is pointing to.

This is a private web sevice for "condensing" long web addresses. It is not opened for the public.

In the future maybe the service will expand and open for other users too.
