If we were aiming to cover the same breadth of information that Serebii or Bulbapedia does, then yes we would likely do it ineffectually. However if our aim is to report only information that concerns competitive battlers, not mixed with a ton of reports about the newest Pokemon Ranger game/Anime episodes/other things that a vast majority of Smogoners don't care about, then yes. We can "aggregate and re-report" specifically chosen news in a form that would be vastly more useful to the average Smogoner, and keep them on Smogon rather than wading through things that they are not interested in on other sites.
Maybe a link on the main page is not required, but a sticky in Wi-Fi (for wifi events) or Stark (for most other things) that is updated by mods with relevant info would seem like a good idea for me.
