I believe the only way a blog makes money is by its advertisers. So that is something you have to think about. What would your blog be about and what type of advertisers would you solicit?
What gift or talent do you have that you want to share with the world? (we know you have many) How would you moderate your blog? Would it be private, members only? Would it be based on one particular topic like parenting, health, environment?
What safeguards would would you install? How hi-tech are you, or do you have friends who can help with the technical stuff?
Hatzlocha Eclipse, reach for the stars!
