Nerdism

Heh, my brother asked me whether I considered myself a nerd.
Short answer: No.

In fashion I consider myself in good taste.
In food and wine I consider myself a connosieur.
In HTML I consider myself an expert.
In games I consider myself an enthusiast.
In music I consider myself experienced.
In literature I consider myself well-read.
In women I consider myself a fan.
In social life I consider myself eloquent.
In philosophy I consider myself a genius.

.. anything else?
