Monetize is a button you can hit here on blogger and I'm sure it puts ads all over your site. Or maybe it causes people to make their site private to paid subscriptions. I used to check a certain blog and I usually disagreed with the commentary, not because his/her thoughts weren't correct, but because he/she never took a stance and had an arrow going up and one going down. Does this help? That site is now a paid subscription! I will reiterate my stance on this once again...I WILL NEVER CHARGE NOR ASK ANYTHING OF YOU! And I'm sure my track record exceeds that of 95% of paid sites. Good luck.
