I Under-appreciated the Kronecker Product...

Today, I came to the realization that I massively under-appreciated the Kronecker product of two matrices.  Until today, I thought that it wasn't all that useful...boy was I wrong!  Kronecker products are wonderfully useful, particularly if you are interesting in networks.  Here are links to a some papers on using Kronecker products as a method for generating network graphs that have power law degree distributions and small diameter.  I will write additional posts on this topic later, as I expect that it will be extremely useful in my own research...
