You would need to be a very special agent to make this work. This is pretty hard to do and keep up consistently. The power curve militates against artificial WOM.
There is also another element which is very well known. It works in the same way that advatorial does. People just don't believe plugs, spin, advertising and all the rest of the garbage you hear from the marketing and advertising industry based on OTS.
Circulation is not king, readership is.
And by that I mean engaged readers. Is an engaged reader going to believe a BuzzAgent? The person who is intruding and getting in the way of what 'I' want to find out. In the networked community, this is a receipt for market oblivion. Its really just another ploy from the advertising industry and WOM will find a way round it.
Remember what we did with 'pop-up' ads and all that jazz.....
