No worries, always good to check how things are. I have spotted a few unimportant things that happen when, for example, someone does not have posts or comments, and the API call can't return anything... It's more an API problem than a your UI problem.

The API should return 0 if found zero things... and not given an error because it can't find any. Anyhow, all and all, quite nice. I love the experience on the tablet, hence why I got one.
