I think every blogger who has been making money online consistently for a few years would have published his own e-book guide on how to build a money making blog. That is why there are so many guides to blog for money through e-books and video tutorials.
May be one day, I too might develop blogging guide outlining my own experience as a problogger.
In the meanwhile, I came across one more e-book on building a profitable blog. I know every blog created ever would have brought some profit to its author provided he maintained it for at least 3 months.
