Do you subscribe to a magazine, news source, or newletter site that provides quality information on running your online business? A useful industry news aggregation resource? A newsletter subscription that is extremely helpful? A site that contains useful articles for making money online? Free or paid doesn't matter (as long as you are not recommending your own). In this day and age, however, a paid subscription requires something extremely special.
Often, resource threads like these have a limited life because sites and publications come and go. Often, even the very best information sites do not survive. Do you know of any that would be useful for EP members?
I know everyone reading this is a member of Experienced-People.net, so the first resource would have to be the Experienced-People Front Page of this forum. This home page contains great articles for running web businesses. As EP does not engage in the blatant profiteering of (most) other forums, this site is a useful resource.
Website Magazine is a well-established industry publication. They have free and paid subscriptions. You can receive a complimentary (if qualified (and every EP member reading this would be qualified)) subscription of 4 issues per year (one every 3 months). The paid subscription is for the mailed print edition. Every few days, I receive an email from them with useful knowledge.
Affiliate Classroom is an example of a great publication that didn't survive, but still has amazing knowledge available online. Even though the last issue was in August of 2009, I still see products, special offers, and ebooks being built around articles that appeared on its pages.
DNJournal is for domainers. They have industry news and cover articles and events related to domain name sales and speculation. The editor and founder is Ron Jackson, and the magazine keeps track of domain sales, sales charts, and the industry's latest news. (Don't miss reading his NameNewbie.com site for a primer on domaining.)
