While I can search just about anything on this site, I think it would be nice to have a browse section for some of the pages. For example I find the recipe section very intruiging however I could only see the last few recipes that had been made, then I had to search if i wanted to see any more. I recommend adding a browse function so we can see other user created recipes based on ingredients, types of food, etc.
Another area a browse function can be incorporated is the Groups area. Its a shot in the dark on how I know what's going to turn up when I search. Is it by group title? Description? all? I think adding groups to some sort of directoy and being able to browse through them would make finding a group much easier. A user can browse to find a group they might not have searched for. For instance I found this group only because it was listed at the bottom of the site under fitness topics.
