In the early days of blogging, blogs were non-commercial enterprises. People sharing with other people just because they wanted to. There was a sense of community. Over time, more and more blogs started advertising and now it is harder to find blogs that exist just to share information the writer thinks is worth sharing.
For example, I have been following Philip Greenspun’s Weblog for years. Greenspun’s blog in its current format has been around since 2003 and he doesn’t advertise. Greenspun has a point of view and I never wonder whether what he writes is influenced by advertising. But that’s rare today both for blogs and podcasts. More and more podcasters and bloggers now want to earn a living by podcasting or blogging. I can’t help but believe that changes the content.
Popularity isn’t all good.
