Right. Case in point. Even though you can get to them through personal connections, you're reluctant to "waste their time." So what about people who can't get to them through 2 degrees of contact. What if they wanted to contact them with an affirmation of the value of their proposals? As in, "I don't know you and I don't want to waste your time, but 83,000 people in this industry think what I have to tell you is important enough for you to drop everything and read."
That in itself is something. Now compare that to the next guy who may be able to say, "That guy's idea is good. But my idea is sooooo good, 210,000 people in the industry think you should read and consider what I have to say."
As someone with limited time, which one, all other things equal, would you open first and which second?
And if the third next idea only had 300 votes and you were pressed for time, you'd skip it most likely, right?
