Multimedia optimized tribe views and snapzines / radd.it style video and music presentation
One of reddit's great strengths is its API, however snapzu for better or worse is not looking to compete on this front. One fantastic use of this openness is a site you may have visited called radd.it.
Radd.it's key feature is skimming any subreddit you post it and converting its links in to a continuous media stream. This can be taking the form of a music playlist or, for videos, something that resembles a TV channel. If you want to try it out, one of my favourites is for /r/artisanvideos.
Given snapzu's interest in (and fantastic capability of!) making magazine type collections of snaps, wouldn't a more multimedia focused brother to this feature make incredible sense and add a great level of big-screen versatility to the user experience?
