Garden of Thought

Okay, I fully admit to being the internet equivalent of a verrrrry slow dinosaur here, but I'm thinking of getting a twitter account - I've never even used twitter thus far - and am sort of circling it cautiously, poking it with a stick.

Question to you twitter people - does it create a lot of spam? I'm trying to figure whether to risk linking it to my email, or whether that will get out into the wild and become a spam target if I do.
