<p>See this blog post I wrote for the CV site, <a href="http://stats.blogoverflow.com/2012/10/voting-behavior-and-accumulation-of-old-votes-on-cv-i-know-i-need-to-work-on-my-titles/" rel="nofollow noreferrer"><em>Voting behavior and accumulation of old votes on CV (I know I need to work on my titles)</em></a>. As of 2012, there was non-trivial accumulation of upvotes for older questions, they are somewhat invisible to regular interaction though. </p>

<p><a href="http://data.stackexchange.com/stats/query/355912/aggregate-days-since-post-creation-that-a-vote-was-cast" rel="nofollow noreferrer">Here</a> I have updated the query to return the aggregate counts of <code>Vote Day - Post Day</code>. Since the data dump only releases statistics on the day a vote was cast, a vote within 24 hours can either occur on the same day (a value of 0) or the following day (a value of 1). In total, these only account for 54% of all historical votes on the site.</p>

<p>Long story short, I don't see any real problems. But increasing visibility to older, high quality posts likely is not a bad thing. A good way to do this and simultaneously answer new questions is to point out duplicates. </p>
