We even posted it to HN but dang rightly rerouted us to this proper Show HN: https://news.ycombinator.com/item?id=33533830
In the meantime, we launched "Scheduled Val" which let you schedule a val with a single click, and it somewhat made hnfollow.com unnecessary because most of that tool helped you manage setting up an interval, tracking its ID, and cancelling it. Now you can just fork this single val to your account and the interval is synced to the val automatically: https://www.val.town/stevekrouse.hnFollowPollJob
The one extra step that akkartik alludes to is also important: you do need to define some folks to follow. How to handle-hold users through this process of forking + customizing vals is a real design challenge for us. Would love any suggestions!
