Hey there! another idea here. RSS feeds, sent straight to the 3DS's notifications. Sorta like RSSMii on the Wii! (In fact, I'd use the same xml format, so that existing users of Luma and RSSMii can use the same xml)
Im sorry @Aurora Wright that the community has been this way to you and other Devs. I'm honestly not very smart and haven't developed anything :P. But I do see the amount of effort you put into your projects and without any pay. You have caused so much joy on these forums. Remember that users like me and others love you for that.
