Blog | Personal blog?

New technologies and new ways of communications always attract new pirates.
When I hit "next blog" on the right upper corner,
most of the times I see one like shown beside... No personal subjects at all... Ads and so on...
Because blog posting is free, some think it is easier and cheaper to send their ads on their personal blogs...
But this damages in depth the spirit of weblogging which is (I think): personal space, personal ideas, personal thoughts.
If I decide to make money with my blog, this is not the right place to do that because although it is my own space,I use another one's creation (template, logging). I must pay for that!
