But in addition to the usual marketing- and sales-related answers, I find that Twitter helps me learn stuff I didn't know I wanted to know. More often than not the info comes in useful.
In a meeting yesterday I described Twitter as the electronic equivalent of a lot of people standing on a street corner shouting their thoughts out loud. For me, the trick is to filter out the noise and be selective about following those I think I'll learn from. Here's an example.
Now the key here for me is that I know @AlexRaymond personally; and, for the life of me I couldn't think why he'd got an interest in counterfeit money! His wry comment, "Probably a bad idea" seemed too obvious ... So I clicked the link he provided and found there's some sneaky technology that apparently prints near-invisible dots on laser printer/copier pages so the device a document came from can be identified.
That's ingenious. It's interesting. I didn't know it. I'd never even considered using my laser printer to counterfeit stuff.
But I did find myself re-telling the info in a client meeting. We were exploring novel ways to deploy technology and my new additional knowledge enhanced my credibility and standing, helping me to justify the approach I was proposing.
