Not really though,
I see most discussion still mostly CS-related.
Aar's Video Game also got more interest than what I have seen on the Undertale thread, although Video Game eventually died a little.
What are you even talking about? I have seen 2 Undertale related forums. And one of them was just about it's similarities to CS. So I don't even know if that counts for a completely Undertale related post. (shrugs)
Are you sure? I really don't see it much. Maybe it's just because I have mostly been looking at the Cave Story Discussion posts. I lurked into the indie posts once and saw a discussion of it but that's probably expected right?
