I blog mostly about earning and selling tips and advertising companies/sites with useful information. I write new posts everytime i come across something informative. My blog is for money based issues but i can blog about anything useful to the reader or advertising company or product.
If a buyer approaches me to blog for him about something, i will certainly do so... i get a lot visiters to my blog on a daily basis
Limitations - What the blogger will and will not write about.
Anything
