There's a difference when I can't find anything on Reddit because there is so much and their means provided for finding subreddits necessitates third-party efforts to ease the search, and Slashdot's random interface constituting a huge question mark. Many, many times I can go to the top /. story in my RSS feed, then go to the front page and not see it there at all.
Slashdot's moderation UI is pretty much the only thing besides comment-nesting that survived the redesign of X years ago, which ruined the site for me and took me from reading most of my tech commentary there down to a handful per month. Good for them and their UI designers, but I'm still bitter. It really is a terrible site to use.
