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.
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.
The big feature I want is I want a way to see what I've already read. I think this is the first app (other than mine) that I know does this.
Haven't played around long but I like you can collapse and expand comments. Is there a way to default them all to be expanded?
EDIT: You need a way to refresh comments.
@Replies: I'm glad you guys like it. Looks like I'll renew my Developer Program membership then. It's due in less than a week.
