Ok... i know what i said before. And i don't know yet whether i was right or wrong. But it is starting to feel like i'm missing out on some good conversations due to not being on twitter so i figured "what the hell, i'm gonna give it a shot". So i've created an account (@davybrion) and i'm just gonna see how it goes. If i like it, i'll keep using it and i'll gladly state that i was wrong about the whole thing. If i don't like it, i'll get rid of the account and i'll let you know why 
. But however it's gonna turn out to be, at least this time it'll be an informed decision.
So... any tips from you twitter addicts on how to keep the signal-to-noise ratio down and how to make the whole experience as valuable as possible?
