That would actually enhance the exchange of articles and information. It also promotes to more discussion about subjects and it gives the smaller tribes a chance to become more interactive with other tribes and members. :-) Combine that with the already well working way of handling content (i.e. great quality assurance/control on the user's end) and you've got this diamond in the sorta rough quite a bit more shiny. :-)

Edit: the automation of such searching is of course the most preferred one.
