(Hey there, Dethdude!) You're right to infer that Miiverse filled the void of an official community hub, but a deliberate conspiracy to draw activity away is a real stretch. 3DSPaint suffers from the same shortcoming the Wii Opera SDK site had: they both had to compete with their respective system's game libraries. DSiPaint didn't have to, which is mostly why it had the greatest success.
I can't simply and singularly say what might save this site, though I do believe it needs to stick to its strengths.
I just feel like it's become inactive merely for the fact that it's inactive. For example, some users stopped using this community, and then as a result more and more left until now there's just us. I know I haven't been 'active' for a long time, but I still check the main blogs page week to see if there's any new activity. I'd love to get back into writing blogs, but enough of my rant.
I think that communities like these will cease to exist in the next few years like this one, DSiCade, 3DSHub, and the countless other websites that just didn't get enough attention.
We've all seen this site grow from a mere painting canvas to a booming population of Nintendo console owners. And it had it's Golden Age. I feel that with the release of the Nintendo NX either next year or the following, that it's going to decline even more (if the site isn't out by then). Given that the Nintendo NX is rumored to run Android it's possible that it will have more ways to socialize with one another.
I think there's a possibility for newer places to come out of the NX given someone make an app of some sort for it. Again, only assuming that it's capabilities of Android aren't masked over by Nintendo.
I don't know. I think people just moved on, but nothing's impossible. They could come back.
I joined this site when I was 15 (I'm 21 now)
I think this community has next to no advertising. Most of the older users have other things to do. This place still holds a dear spot in my heart (met friends, found first real minecraft server, ect). I know I wont use it anymore though. It would make a great app for a mobile device, like a video game discussion community. I think life can be breathed back into this but not without some changes and additions.
I think we should make an android app. And advertise as much as possible.
