I actually disagree with this. I find that customized Reddit leads to the same feedback loop/conveyer belt feeling that made me quit Facebook out of annoyance with always seeing the same ideas propagated out again and again. Browsing Reddit without an account lets you avoid the urge to comment on things and also turns you on to loads of new things that you otherwise might not've found on customized Reddit. Granted, I still have an account I use sometimes, I just get more enjoyment out of the front page when I don't have any control over what I'm seeing.
