Things to Consider: Time and Money

Higher time investment, lower money investment
Your financial costs a publisher will be considerably less online, but your investment in time will be about the same, if not greater. You will also need different skills in and online environment, such as HTML coding, and using FTP to edit your documents once online.

Lower financial reward
If you plan on spending a lot of time and effort putting together your publication online, don't expect to be rewarded for it financially. The way it stands today, advertisers will most likely not pay to have their banner on your site. 

Print is still the only option if you don't want to be guaranteed of "volunteering" your time. Decide right away if you are comfortable with "giving away" your work. Online, you will most certainly provide your work for free, but this will mean more time for content , and less time worrying about advertising sales. In print, you have the potential to make money, but you will spend a lot of time focusing on how to accomplish this.

Looser deadlines
Meeting deadlines in print means dealing with content as well as advertising, which can be stressful and frustrating. Online, your deadlines are self-imposed, and you will most likely not be worrying about ads.
