Another issue I've seen from some of the more prolific YouTube channels is they slowly become another mouthpiece for "news coverage". The algorithm very much expects you to continue uploading, because everyone is always looking for the newest content; at least before YouTube removed the Trending section. I admit that I only really check my Subscription page at this point, and after going through a subscription purge I only see maybe a half a dozen to a dozen new videos. Its actually been very useful since it encourages me to not get sucked in to watching hours of videos.

However, given my experience during Digg's v4 attempt this past year, I will say being willing to put yourself out there has served as a pseudo-networking activity and I've gotten the chance to speak with several people and now I'm giving talks "out there".
