Reddit? I see lots of comments about how people are amazed Reddit has remained (or, really, grown) as popular as it is while still having a very &quot;low rent&quot; UI.<p>I&#x27;d actually argue hallelujah that reddit hasn&#x27;t significantly altered their UI. It may not be pretty, but it doesn&#x27;t take that long to get used to its quirks, and when you do it is extremely fast and easy to navigate and find meaningful content. I contrast this to slashdot, who proceeded to make their UI WORSE with every update (more &quot;modern&quot; styling and response, but they made it totally broke the usability of their commenting system).
