Not many bloggers do this, and it's probably more slanted towards those who have been blogging for a while and have built up a regular audience, but it's something worth thinking about a little further down the line.
Think of it as a way of providing an extra option for people that have read your blog for a while. As well as providing your usual blogging content you can also set up a private area of your blog which people would have to pay to get access to.
The key to making a success of this is to ensure that the extra content is worth the money. Providing much longer blog posts which essentially amount to an in-depth report on a subject are a good way to attract people's attention. Share and Enjoy!
