Viewing comments on our mobile apps would be useful, and it's something that we can do. Our feature roadmap for the next few months is already pretty filled with exciting features as you can see, but adding comment viewing into the mobile apps is something we can try to fit in.
After you're able to view comments on our apps, we'll also want to add in the ability to write comments from the mobile apps. Like I mentioned in response to your question about guide creation on the iPad App though, the second part will take some time, as it requires us to first develop an authenticated write-API, which is still a few months out.
