How many blogs is too many?
I responded to a discussion going on at Ryze.com about the number of blogs each person has, and whether that number reflects the number of email addresses that person has. For instance, a school-related blog that is based on your school email address vs a personal bare-it-all blog that's associated with your free hotmail account.
I've been going back and forth on the issue of how many blogs is the right number to have. I started out with several blogs but then narrowed it to two...one on nonprofits (called Net Present Value) and the other on business/technology...this one called Ready Fire Aim. But it is hard enough to blog each day on one blog let alone multiple blogs...and so I decided that I was going to focus my attention on one blog.
And since my opinion and interests color all my blogging, I think Ready Fire Aim can be broad enough to include the kinds of nonprofit stories I wanted to highlight in my second blog...usually about the management or strategies of nonprofits etc.
On Blogging Network I've found that some of the more prolific and popular writers have several blogs in many of the 19 categories. But that takes dedication and time to come up with interesting things to blog about regularly on multiple blogs. And may result in more abandoned blogs than if each person had just one blog they were focused on.
I think we'll see the majority of people settling into having 2 blogs (if at all) in the long run -- a personal, fun blog with photos and rants and all -- and a professional one that builds their brand and promotes their expertise or knowledge in a certain field.
