This is pretty good. I wish there was a way to go directly to the comments on a post, but I don't know what UI would work for that.

A few other thoughts:

* Profile > Edit needs a cancel button. The only way to get out is to re-enter your username. Or maybe just make it go back to the old value if you enter blank.

* Long usernames tend to make the description line run off the screen and end with "...", which is a bit messy. Maybe a smarter truncation algorithm?

* Swiping left to right on a story seems to work inconsistently, but I'm not sure why.

* The comment view is just about perfect.

Yours is my favorite, btw. I added an interesting feature to go beyond seeing what you've read--it indicates what you've already decided NOT to read.

I often find I choose to ignore certain posts but they often stick around so I reread the headlines. Pivit shows an orange indicator on brand new posts.

Re comments, I could add a feature to expand all if I get enough requests, but after some use I've found this to be optimal.

I use the one written by you. Nothing to add to the conversation, just wanted to say that I like using it. Thanks.
