The latest company to jump into user-generated content: Nokia. Nokia just launched their own social networking site, MOSH, allowing users to share all kinds of media from their PCs and/or mobiles, including audio, picture, video and applications. The processing of video is similar to the YouTube approach: i.e., whatever is uploaded gets crunched by a back-end server and turned into (in this case) Adobe Flash format. But I wonder how scaleable this approach is, surely you eventually reach a point where the volume of offline processing needs a football pitch of back-end servers?
