When we picked out baby names, the first letter was really important (to name the kid after an older family member) for browsing names, but I guess some people want to search for a specific name.
I used to have the tables sortable, so we could re-sort the names based on least popular. The idea behind the clusters is that if you like a popular name, but it is too popular, then you can immediately look at its "cluster" and see all of the related names, then pick the least popular variant.
