It's all here.

Sometimes, I am quiet jealous with my friend who have a very good income. Being a full time blogger is one of the best job in the world but I wonder why they not list it in jobs in sales.

Is there any reason for them to not list it?
Or perhaps blogger is not a "profession" that should not to talk about?

Well actually, that is the special thing about blogger that we should know. But if you are not a blogger, you must find the job that can suits you. That is true!
