Yes, it's not a cheery thought, but think about it. At the end of the day, it comes down to the client/company. Do I know what the problems were with Congdon and Baron? No, not at all - and none of us are privy to those discussions. But, we can all agree that 51 trumps 49 in percentage.
And, the fact is that I was never a big watcher of Rocketboom, so this does not affect me much. If I want my pretty vloggers, I have Rachel at 88Slide and AmberMac - and I think they both are much more talented than Rocketboom (I was alive in the 80's, so I already saw those skits, thank you). I almost forgot to mention the hottest - and one I've known the longest - Irina Slutsky of Geek.tv. But, man, I always try to keep the personal out of the blog.
But, you can be macro ruler of a vertical space in the blogosphere, but you make one mis-step and you can find yourself with a pink slip. You can wear one or 1000 hats at a job, but if you piss off the wrong people, you are shown the door. You can be that lovable scamp, but getting the job done is more important than blogging.
I had this discussion a year ago. During the dotcom era, there were superstar CEOs that became the story. They probably thought they were irreplaceable ... until they were replaced by the VCs. And, while bloggers are making a name for themselves, at the end of the day, many of them answer to another master ... the paycheck.
