A couple of interesting developments today that bring social aspects to large content sites — specifically, YouTube and eBay. The former, which hasn’t really had all that much of a social-networking bent to it (apart from comments and the ability to embed videos elsewhere) has launched something called Active Share, which lets you see who has been viewing your videos.
Meanwhile, eBay has taken a page from YouTube’s early success and added the ability to embed auction-tracking widgets in a webpage, so that people can follow an item without having to reload a page or get an email alert. Both of these make total sense to me — to the point where I’m almost surprised they didn’t already have these features.
