Video sharing monger, youtube, launched there new widescreen video player recently. This came after months of speculation by community members boasting that youtube was moving towards high definition. Certainly, this move towards 16:9 widescreen video playback is a step toward direct competition with other video sharing silos such as vimeo.
In all of this HD frenzy, the core component of youtube is being severely neglected. Community is what has made the site explode into the central hub for video sharing and overnight internet celebrities. Arguably, the pseudo-HD experience would elevate the effectiveness. I guess it is too early to say.
