I think there's a critical bug on when user's activity is empty (seems regression)

Seems a regression from this
The next update will have a change that should fix this. The feed will now look back up to a month for items, in case the newest page of contents is blank. Let me know if this fixes it for you. — Kasra Rahjerdi ♦ Aug 11 '14 at 17:22
Unfortunately, the info is a bit spread to some posts, but from what I see: anonymous feed is not buggy [1] [2] [3]
Or possibly, after reading Kasra's comment, the real issue is if the account is really a freshly-new account (user just creates a new account from the app). If it's, then it's not a regression, and it doesn't contradict with his comment.
So... my current proposal is to use anonymous feed as the initial feed for them as the starter, then continue to populate the feed after the user has more activity
As a matter of the fact... some of the reporters have 1-and-only-1 post, that is, the bug report itself, thus they haven't had any activities before that.
