Hi, I wonder why PBN have to host in selfhost instead of using 'free host' on wordpress.com. Can anyone tell me what is the different between selfhost + domain and web 2.0 + domain ? I see some guys sell $10-15 per post on some sites like travelpod.com, Behance.net, Storify.com, etc. After checking it's like web 2.0 nothing special. Please help.
