This is how it works: there are ninety minutes scheduled. You dial in and bring up the website at the designated time. When the event begins, you are moved around randomly every five minutes. A clock ticks in the right corner of the screen allowing you to see how much you have to say (both of you). When the five minutes is up, you are automatically pulled away from that person and wait thirty seconds for the screen to change (you see that person's profile so you immediately get an idea who they are). You can exchange numbers or tips or ideas with anyone, even those with whom you have little in common. At the end of the ninety minutes, everyone's name you were matched against comes up and you can send an email. I sent seven and received close to the same amount, but not necessarily the same people. I have two follow-up appointments, one with a recruiter and the other with a writer.
Why is this good networking? You can do it from home. You are forced to connect to people. You cannot waste any time warming up: you are there for a purpose, and you quickly get to the point. You have an obligatory departure so you don't have to walk away and feel guilty. You can see the person if they posted a picture and you get all their information in front of you, not just a name tag with a company name. But the big prize is this: you have an immediate chance to follow up. You don't go home from the event and look at the business card and enter it into your address book and then wonder when you'll contact that person or why you wanted to in the first place.
This is VERY GOOD business. Try it.
