It could indeed be interesting, but also time-consuming. The points above made as there not being so much of a "snowglobe" of forums these days do seem to stand true and communities are left to their own primary focus. But if this would be done I also agree that the administrator shouldn't take on the task and possibly hire someone to do the searching out of forum news. The internet is massive and some forums may think you are favoring them by putting them in the spotlight when their forum wasn't put in the spotlight. It's a tricky thing to commit to.
