Anyone know of a service that will summarize a batch of different news letters for you? Say you subscribe to 30 newsletters, but a lot of them contain fluff, legal & disclaimer, ads, etc - but you only want a summary of the good content sent to you on say a Sunday. I would imagine the interface being a list of newsletters, with a drop down to say how much of the content you would like, an option for what time and what day you wish to recieve the summary and then the actual email to just be the summary with a single link to the full newsletter underneath. Does something like this exist? My google-fu is returning nothing.
