Looking for a youtube meets flickr clone, where users can upload/host their content. Functionality needs include: -ability to upload user generated videos -possibly down convert video to web friendly size, altho if you can recommend a streaming process that eliminates that than OK -ability to tag videos and search by tags -'clustering' of videos according to tags, a la flickr -user generated ranking/voting -friends list that notifies you of new content/comments added by your friends Would prefer someone familiar with web2.0 trends and methodology. Need sampe sites, etc. Thanks.
