I have signed up to three different paid blogging sites and I have other pending application on other blog ads. Truth is, PPP has always given me the best opportunities to earn extra cash. I've been a member of this awesome site for less than 3 weeks and yet, I have already raised less than $100! Though, it's really not that much for others, a $100 for me is decent and more than enough for me to cover some of my monthly expenses (phone bills, cab fares etc.) I am just grateful enough that even though my blog has a PR of 0 and I'm only using a blogger account, it doesn't prevent me from getting some opportunities.
I do not really intent to flood my blog with sponsored posts but having one or two every once in a while will not hurt my blog either. Besides, I'm setting aside a fraction of my blog earnings to cover the blog hosting of my own domain for one year coverage, something that I am really serious of accomplishing in the near future. :)
