how good are blog traffic, and what about ad prices?
 

im going to set up a multi user blog and got about 1 every second day that is interested in one (signs uo to my newsletters about the new site blog + reserves a blog name).
The site costs about 8k to develop so would be interesting to know how much i can make from blog traffic if i have ads on every one. Im sure i can get 100 members in 6 months without advertising so alot more if i advertise the site
