It has been said on many occasions that the blogosphere is an echo chamber. Whether it is or not, it generally brings good, new content to the eyes of many. This works because each person with a blog subscribes to a heap of blogs, and they point to interesting things they see. So, given a couple of iterations most people will have seen something pass through their aggregator.

This is very similar to the Brazil Nut theory where the smaller particles work their way under the bigger particles and push them to the top.

That’s all fairly obvious and elementary, until you add the meme-trackers to the frey. People start going to Memeorandum for their fix. This works by watching a certain group of bloggers and pointing to stories that start getting a little bit of traction. Problem is, that people like Robert Scoble who has been one of the best linkers start using the Meme tracker and stop reading the same content. In essence, he has only been linking to what has already worked it’s way to the top.

However if everyone who Memeorandum was watching, only watched Memeorandum, nothing new would ever be come to the top, unless of coursed it was produced by the memetracker’s list. In essence, this would be like having a jar of brazil nuts, with no peanuts to help bring the good stuff to the top.

So Scoble, thank you for trying to shake the jar and bringing the good nuts to the top again.
