The iPad is a wonderful device to watch videos on, and a number of startups are aiming to provide users with interesting new ways to discover the best videos to watch. Most of these apps -- like Showyou, or Squrl, or Fanhattan, or Shelby.tv -- have some sort of a social discovery component, which allows users to see what their friends are watching, and conversely, share other videos with them. Most of them also tap into freely available videos on the Internet, although they occasionally partner to surface videos from major content players like Hulu or Netflix.
There's another app maker that is taking a stab at powering social video discovery -- but it's doing so a little differently. For one thing, the new Ringz.TV iPad app, from RingGuides, is designed a little like an old-school electronic programming guide, but on the iPad. It provides a concentric ring of videos and content providers, which users can drill down into to discover more granular pieces of content.
