There are LOTs of online magazines. I came across Suite101 this past weekend. Articles are written by "experts" and organized by categories. I have to admit that I lost a couple of hours surfing through the site. It's all text-based but has enough to keep you busy for a while - and they are looking for free-lance writers!
With 12 years online, over 150,000 articles and more than 2,000 professional, paid contract writers, Suite101.com is dedicated to delivering great articles by skilled writers.
