I feel almost bad creating an “emotionless” link to this post, but whatever.
Prashanth makes good points, and I really do think it’s the biggest problem with tumblelogging: it’s basically del.icio.us with a feeling of authorship, but so many tumblelogs don’t take authorship seriously, and add nothing meaningful or thoughtful to the content that they post and don’t own.
It’s a paradox because uninteresting assholes are blogging easier, but genuinely interesting people who normally wouldn’t have time to blog are tumblelogging.
I think we can take a 70s sitcom’s wisdom: you take the good, you take the bad, you take them both and there you have. The facts of life.
I disagree, tumbloging is whatever you want to make it. I try to add commentary and my own comment to as much as I can. To a certain extent it is a bit of an aggregator for these other services. But the only tumblogs that I follow either have a unique view on things or provide interesting commentary. I have digg etc in my google reader to look at all of these things, the people I follow create their own content which is worth reading.
Tumblogging can be whatever you want it to be
