Design is an essential element of functionality. I had to click on one small link at the top of the navigation bar to get to the most important information: Users.

Then I had to scroll through a list of people, pulling out various tags and keywords that might have been interesting to me.

I gave up finding what I was looking for, but not before clicking on 'Search' at the top. The search wasn't an autocomplete field, so I typed in something, hoping for the best. 0 results.

A good design, IMO, makes the most important function the most obvious feature. It makes the most complex task the most simple to complete.

For this site, I could have used a sortable and searchable data table that let me both browse, search, and communicate on one page.
