Subreddit Time Machine
Okay, it's just "top by date", but this sounds so much cooler.

Notes
- This will redirect you to a page on reddit showing the top submissions (max 200) posted to a subreddit on a particular date (UTC).
- Unlike the rest of stattit, any subreddit works here, not just the most active ones.
- You can link to specific dates with an address of this form: http://stattit.com/r/<subreddit>/YYYY-MM-DD - so for example, to link to the day that /r/Games launched: http://stattit.com/r/Games/2011-11-16
