It’s a fair question.
I have this blog, a bunch of others, and I start with a bang and my momentum fizzles out completely. The conventional wisdom dictates that you should keep a blog tied to a theme. I have a blog about what I do at work at marketingstartups.com. I had another where I wrote with a pseudonym to conceal my identity because of the whole “don’t write anything your future employers might find offensive” school of thought.
Rather than having 5 seldom-updated but perfectly focused blogs, I’m going to make this blog the KFC bowl of blogs. I’m going to toss everything in here and see what happens. What do I have to lose, right?
