Quality vs quantity
@ Julian: I agree with your implied preference for quality over quantity. For my part, I'd a thousand times rather have just 3 friends I can rely on when I need them, than 1200 acquaintances who'll scatter like cockroaches when the going gets rough. A small contact list isn't the mark of a loser; it's the mark of someone who shows good judgment in choosing their friends, whether online or IRL. Such a person is more likely to be someone whose friendship is worth cultivating, in preference to someone interested only in the wank factor of being a Web 2.0 social butterfly.
@ Simon Greenwood: I love it when I see someone reduce one of my wordy missives to such a simple, clear sentence. Well put! :)
