Browsing people, topics and questions

It's hard to get a view on who all the people are on Know Between, what all the topics are and what all the questions are.

If you're not logged in, you get to see how many topics, questions, responses and people there are, but you can't click to browse them.

If you are logged in, you can see your friends and friends-of-friends (who share interests), but again there's no holistic browse.

The search feature indexes topics and questions but not people. It would be good if you have a friend called Eric to just search this rather than trying to find the link hidden somewhere.

I suggest the following updates:

1. Display the number of topics, questions, responses and people always (whether logged in or not)
2. Support browsing of all topics, questions and people
3. Show people in search as well as topics and questions.
