I've been a member of this forum for a _very_ long time and I've been visiting regularily since forever, and there has
always been people posting about stuff unrelated to the Amiga.
While this is first and foremost an Amiga-forum, this is also an entire community of people interested in electronics, technology and new advances in general.
We had regular astronomy updates for a while (whatever happened to Blobrana anyway?) and enough wierd-ass discussions to set off an entire array of Brittish porn-filters.
This is Amiga.org. This is where we go to discuss interesting stuff with people we've been discussing with for a very long time. This will not change anytime soon, but let's face it - the ammount of Amiga-related topics is going down fast, and that means there will be more and more other stuff here.
The alternative would be that the forum died because there was too little news.

EDIT: Why would anyone need a 300 GB disc anyway? Isn't cloud storage the rage nowadays?
