Pls anyone using media.net should pls drop his or her contact and also give a brief summary on his/her experience I am considering going into it but have no idea

Media.net is almost as hard as Google AdSense, before you can be accepted, you must have quality content on your blog as well as 60-70% traffic from country like the UK, US, Canada and Australia.

For me, Google AdSense is better. But if you blog is targeted at readers from US, Canada and the UK, you can try to see if you will be accepted. Most ad network, don't work for country like Nigeria because their major advertisers are from tier one country like the list countries above.
