This is an Internet Community where the members can exchange funny or worthwhile files of different kind. This is quite similar to YouTube where video files are uploaded, in order to enable other people to watch them. Here it is very similar, but you may upload nearly every type of files.
You are invited to have a look around, without having registered.
Of course, it is free of charge, like lots of other communities in the web, but here advertisement is minimized in contrast to YouTube and others.
Just test it and look through what is available of funny, interesting and spectacular files.
