I want a context button

I have been on a search for a context button.  What is it and why do I want one?

When writing about my, your, our digital footprints it has become obvious to me that just putting the date and time on a post is a bit of a nonsense.  It is far better to leave the date out as it ages the blog post and if it is old it may get skipped (why read old stuff).  However, when searching I want the date on articles so I can tell if current or relevant.

Date ages me but what I do want, however, is a content button.  When someone comes to http://blog.mydigitalfootprint.com I think it would be good to have a button that says CONTEXT on each blog.  The button takes you to a service say from WSJ, Times, Guardian, NEWco etc  and provides key (contextual) stories of the day/ week/ month that are relevant to the blog.  It could be presented as images, text or  video, lists etc, but is a summary of what was happening about the time a blog was posted and hence provides some context.   I would love it if users could decide about the top stories by category on the day, which then provides the historical context of that day in history.

Please let me know if you have this service or want to develop it.
