I saw a WSO the other day offering PLR articles via subscription. Not so much access to a PLR site, but actual content delivered on a schedule (I suppose via email). I've been doing a little thinking about that, and I'm just curious how many of you are currently offering a service of this type? An article a day, a set of articles per week, etc. I'm partly trying to judge how many people are doing it and how well it's working for them, but any thoughts or tips you have to share would be great as well.
