Encyclomedia is a video encyclopedia that is great for searching for articles and videos on any given topic (think United Streaming). What separates this from just any other search engine is to then take those results such as video and then share it w/ others via an embed code.
Do you wish YouTube's embedded video player was just a bit better? If so, try out EmbedPlus. EmbedPlus adds scene-skipping, annotations, zoom and more playback controls than the embedded YouTube player.
