I used to use this interface, but then I noticed a bug (or interesting feature, depending on your point of view) in that when you were viewing the top 10 or top 20, and loaded more articles, some articles would disappear from the list.<p>My theory on this is that it was caused by loading articles a certain number of hours back from the current time, and then grouping by day before sorting to the top X.<p>For example, if the last 24 hours were loaded, and grouped into today and (part of) yesterday, you would get an accurate top X for today so far, and an accurate top X <i>for the portion of the previous day it had fetched</i>.<p>This was particularly noticeable when I hadn't visited for a few days (I've since rectified this aberrant behavior of mine) and loaded a few past days to review missed submissions. Seeing something that caught my eye disappear as it loaded older content drove me nuts.<p>It looks like the problem is fixed now, but it's hard to be sure, as it may be more or less likely depending on the time of the day you visit.<p>I sent a bug report to the developer when I noticed this (in February 2013), but never heard back. I'll happily go back to using this interface if it's fixed though, I found it generally more pleasant to use.
