You know what? Only last week I was wondering why no-one on BA does this.

There are LOTS of non-travel blogs where the owner of an average blog pretends it is massively successful and starts a sideline in telling others how to start a blog. The income is very chunky due to the massive commissions paid by hosting companies. Behind credit cards it is probably the best income stream you can get.

There is one home blogger in the US who publishes her income statements to encourage other bloggers to start up. Forgot the URL. BUT if you can decode her statements, you see that most of her money (mid six figures) is not from the homeware blog but from commissions from Bluehost etc getting others to start a blog.
