If you want to get a top blog you need to write about politics or blogging itself. That’s the conclusion you can draw from a year-long study by Internet metrics analysts Nielsen. They measured the top blog postings according to how many people commented on them and how many links each blog posting received. By this measure the most popular blog posting of 2006 was one on the blogging system, Live Journal. However, six out of the top ten posts were on American politics. The remainder were all on blogging. The top 100 posts of 2006 were based on the same two subjects plus the addition of humour. My own research shows something similar. A year ago I set up Newsology, a test blog which looked at the psychology of news, including politics. I haven’t posted to that blog in over a year, yet it continues to attract readers and subscribers each week to its RSS feed. Clearly Internet users are interested in political matters; if you are running an online business, writing about the politics of your sector could therefore help boost your readership.
