Reading a blog is a lot like standing at a crowded bus stop and hearing snippets of conversation. If something catches your ear you will maybe even try to get a seat close to them when the bus comes so you don't seem to be listening.
For the most part, it is a blur of noise, blending into itself and of little known significance or relevance. Sometimes, though there are blogs that capture people's attention. Generally, I think the most successful blogs are about politics. If you write about politics and offer some sort of insight, on a regular basis, your blog will become successful.
Gone are the days when somebody could become rich and famous because they decide to write about cooking everything in Julia Child's cook book. The field was much less cluttered back then. There was less to read so it was easier to get noticed.
Having a successful blog means being a real expert on something and updating it consistently about the same topic, building a readership and a reputation.
For everybody else, it's just a glory project.
