I was trying to show Academia.SE to a friend yesterday, and let him browse a bit. As we were using his computer, not mine, I obviously wasn't logged into my account.
I was surprised that even after 10 minutes, I couldn't find any link to the highest voted (answered) questions. When I am logged in, I would click on questions and then I would get link-options: newest, featured, frequent, votes, active, unanswered and I'd chose the votes to get to this content. However, when accessing the site anonymously, the only sub-link I can access is newest.
I also tried all other link-options I had, thinking it might just be slightly different when not logged in, but no luck finding it.
I am hoping this is a bug: I would assume that it is in the community interest to show those questions. After all, those are the best questions and answers this site has produced, excellent for new potential users to get interested and/or familiar with the website.
So, if this is really a bug, then this is the bug report. If it was done on purpose, I would be really interested in the reasons for not making our best questions easily accessible to new users.
