On PageRank

Pageranks are dropping like flies. Even those that are not doing paid blogging have found their blogs being slapped with a 0 PR. I wonder what Google's reason behind penalizing small blogs? I do feel bad about those who are using blogging to pay the bills. Using your earning to go ga-ga over online shopping is one thing but if you need it to augment your monthly income, then you'd be terribly disappointed. I know I will! I once used my earnings to pay for our old credit card bills and it was really a huge help. I hope something new and an even better way to earn money online will come out soon.
