I absolutely agree with this. I spend lots of time pokewalking at a particular park and the other day I looked up from my phone and was honestly surprised that there was no physical building where I expected the Gym to be.
I wanted to like Talky but I tried having a large group conversation there (10-12 people) and it was laggy, some people couldn't see other people, and other people would drop from the call randomly. A few of us had fiber connections but it didn't seem to make any difference on the connection quality or reliability. We had to move to Hangouts just to be able to hear and see each other clearly.
