Tag Schema Discussion

[unboggling]

I'm hoping to get some better ideas regarding tag schema from your discussion and comments here. What tag schema do you like to use? As a calibre noob recently, it took me weeks to get acquainted with using tags.

Here's the tag schema I'm using now.

Genre Abbreviation Key
(Font should be monospaced)
------------------------------------------------------

It's helpful to use abbreviated tags to be able to 
see them all at once in calibre's Library View. 
Performance is improved using fewer and 
more applicable tags, rather than hundreds that 
apply each only to a few books. It's good 
to replace the original tags with better tags 
just after adding books to a library.

Prefix sort in calibre is     .a, (, [, noPrefix, zABC
Calibre doesn't like these    {, |, ^, #
Excel doesn't like these      +, -, =, /, *, ?
