The scrolling is not smooth yet but early feedback is appreciated. Thanks!

Great, looks good. I wonder if - (void) scrollViewWillBeginDecelerating:(UIScrollView *)scrollView is contributing to the slowness. You're calling [self fetchData] twice for some reason, and triggering a network request every time the scroll view decelerates might be too aggressive.

To make it more conservative, keep the code in the same method, but check against contentOffset and only trigger a load if you're near the bottom of the feed. You can also maintain a loading state, and have fetchData do nothing if there's already a load in progress.

Thanks for your feedback. I was experimenting with prefetching two pages of data and checked in the code to call fetchdata twice. My initial stab at implementing conservative fetch is tracked by Issue #3 .
