Nice, good work on the initial pass.

I think we could have a cleaner hasMore logic by having the reader track the current count vs how many items total are in the notes collection.

Also instead of storing notes in an array we should render them out as we get them. For duplicates, we can just not bother tracking duplicate notes when rendering the randomized timeline.

Also, we should start doing a page render before ingesting followed accounts to improve initial load.
