Finnish vendor Nokia continued its foray into the social networking space this week, with the beta launch of its own social network.

In a typically Finnish reference to the heavier, darker side of music, the service has been dubbed Mosh and apparently aims to fill the gap between mobile and desktop-based social networking.

Nokia, as the world’s biggest handset manufacturer, is in a prime position to be able to develop a decent experience of social networking on the mobile, something the more desktop-based sites are still struggling to do satisfactorily.

The desktop version of the site is accessible at mosh.nokia.com, while the made for mobile version resides on mosh.nokia.mobi and shares all the same features of its desktop-based sister site.

Users can upload a variety of files – audio, video, images, applications, documents and even games, which should prick the ears’ of the lawyers up, as it could pave the way for the sharing of copyrighted content. Or at least, that’s what the music and video industries will no doubt claim.

It’s more likely users will use the service to swap filth. Some of the most popular tags already are “babes”, “sexy” and “topless”.

Subscribers can then communicate with their peers by SMS or email, to let their network know they’ve uploaded some smut presumably.

Nokia doesn’t make it clear whether Mosh is anything to do with Twango, the US-based media sharing service it acquired late last month.

But Twango is a platform for organising and sharing photos, videos and other personal media and gives Nokia a tool to allow users to share multimedia content through their desktop and mobile devices – which sounds a lot like Mosh.

Twango was a privately owned company founded by former Microsoft veterans.

Like the Finnish company’s developments in the widgets space, with Widsets, the Twango acquisition and Mosh are part of Nokia’s longer term strategy of combining its Nseries “multimedia computers” (phones), with an always on connection and a rich media sharing destination.
