What is the planned intention for an upvote? Is it (1)I'm interested, (2)I applied, or (3) just keeping it ambiguous for now/undecided.
How are you finding/tweaking the ranking function? Most posters will probably not try to game significant support, but could for an additional one or two votes to gain a relative advantage. I imagine potential applicants will scan the whole list anyways, but did you consider a solely time-based ranking with no voting -- what HN seems to do for YC job postings currently?
EDIT: For example, I noticed someone submitted < 1 minute ago with a default score of 1. The posting, although submitted most recent, is ranked last and is on the second page.
Also, there are a couple times where a single company is posting separately for each position instead of consolidating to one thread. Is there any concern about a top-tier tech company owning most of the first page with many different postings? My apologies if these questions are a little premature -- perhaps we need a "Feature Requests" thread.
