An existing control looks like http://demos.devexpress.com/ASPxImageAndDataNavigationDemos/NewsControl/DataBinding.aspx
Where this control would allow you to express the UI of the aggregated feed data, where as the feeds from RSS or LinkedIn, YouTube etc can be sorted, grouped, stared or shared.
So ideally feeds can be added at run time. Personal settings could be saved using existing tooling.
The ideal solution would allow the end user to customize their feeds.
Ideally it would degrade well onto a mobile interface so you can flick thru all the feeds, flick to the left or right to dismiss or save. This is a bit more KendoUI
