Hi Andrey,

I thought I understood quite well the difference between a graph-store and 
a graph-layer (on top of other storage structures).

Recently I have been reading up on a lot of stuff and there seems to be a 
common misconception that all graph stores use indexes for traversals.

This may sound strange, especially since "index-free adjacency" is quite a 
transparent description, but attempts to explain the difference between 
graph databases and relational databases have clearly not sufficed.

Regards,
  -Stefán
