VodPod lets you collect videos from web sites with a browser button (if it is able to find an embedded video in the page) and it lets you follow people who collect videos as well (and be followed) . It recommends people based on the tags put on videos. Your collections can be used with widgets (as above), and you can share your videos from your collections on Facebook and Twitter (selectively while adding or watching).
There’s a variety of widgets/buttons ready to be used with the usual blogs or on your web site.
A free account offers three collections you can name and put videos in (as above). Getting five other people to subscribe via an email invite or a link (such as this one) gets you a Pro account with some more options (including more collections). Alternatively you can use their yearly rates with Pro or Pro+ accounts. See the VodPod site for more information.
