Okay, I seen enough of this. First, this is being honest, not disrespectful or mean by any means.
Your initial post was this.
If you looked at other people who do post like this one.
https://gbatemp.net/threads/release-virtuanes-for-3ds.465461/
There is a list of what is featured, and not featured, what is planned and even a download link to a working version of the project, even some pictures. If you was gonna present a project to someone, Make it presentable.
Show something worth getting someone's attention. Please don't create post of "Starting a project" without any proof of concept. So already, your presentation is hugely lacking.
Second, if you want feedback, you need to accept criticism. Was you making it for yourself or all of us? If you was making it for yourself, then you don't have to be here or ask for any feedback. If you was making it for us or anyone for that matter, you have to be open to all feedback, even disrespectfully harsh rude ones. I'm not saying you have to agree or like everyone's opinion, but least listen, consider it and act like you are trying to work with the community you presenting this to. Yes people say nasty things, but what do you expect when people have been through the same kind of stuff all the time, people already aren't open to things which doesn't give people enough reason to care. If you don't show people you care for their concerns, you already messed up with the community.
Last, I dunno whether you are considering making this project real in the future but I would like to see it working just as it does now if possible. Simple Miiverse posting i have now on 3ds/wii u in this new "Miiverse 2" Also please use a different name, and assets that doesn't take too much from nintendo as people said it gives them enough reasons to take LEGAL ACTION AGAINST YOU. If you succeed, I'm glad you did and appreciate you keeping a feature our game consoles have. If not, then I dunno what else to say, not many would seem disappointed by it but I hope you do your best.
If you messed up the presentation, you already lost all hope of anyone reading this. There is people out there nice enough to tell you what you could do to have fixed this or prevent this dislike train that has started.
@Lilith Valentine was clear and helpful with her post, but someone else could have easily just reported it and called a mod, having them decide whether or not this was worth keeping open to allow others to continue these comments. You are better off just continue your project and when you present WORKING PROOF OF CONCEPT that you managed to replicate miiverse, then come back and post this content, instead of continuing to post more and still haven't managed to convince them is real.
Once again, i wasn't saying this to be mean, I was just pointing out a few things, hoping it helps you.
