List of digital currencies?

[grarpamp]

Any links to a list of digital currencies organized by technology?

ie: Bitcoin has countless forks characterized by nothing more
than adjusting (or not) the operating parameters of the bitcoin.org
code and starting their own genesis. Others may swap out the
hash or crypto functions within that. While useful to list them
all under the aforesaid parent technology 'Bitcoin', they are all
ultimately uninteresting and a waste of time to research.

A real list would group all the digital currencies by genuine differences
in architecture... those archs thus resulting in their suitability to different
applications, capabilities to anonymity, features for centralization/regulation,
etc.

So now you might have
Bitcoin
Paypal, Linden
Some other various coin designs
Currencies that pass serialized 'banknotes' around
