I love the initial letter graph! I like stats to begin with, but I especially enjoy seeing things like the male/female graph for the O is virtually the same, while for example M seem to be mirror images of each other.
I love new toys! The 'grouped to sound' list took me a while to realize what I was looking at. I realized only after viewing the 'more loosely' one. I clicked to quickly and didn't read the part about hoovering.
When you search for a particular name, for example James, it only shows the sound 'james' / 'gamas', but you can't see here which names were used. Would hoovering to see the list be an option here as well. Otherwise this image:

Might be difficult to interpret. To me at least :)
