Umm tricky question... but maybe yes I will write about a product if they are offering me good money. don't get me wrong. i m not that much greedy for money, but also I will not ignore ati hui lakshmi. I have supporting reasons:
All of us will agree to this that blog is a media like newspapers and TV channels. Have you ever heard a newspaper refusing to advertise a product just because it doesn't go in sync with its philosophy. In the classifieds, a large number of the ads are from obscene or fake advertisers. Or refusing to advertsise or PR some product because it earlier glorified its competitor. No. So why us?
Agreed that a blog is more like a personal diary where you post things that you personally feel for. I have a solution. I saw this being used by some blogger, i don't remember who. After talking skies about a product, the blogger wrote a P.S; it's a paid post.
So if you are fearing that your readers will be astonished at your change in philosophy, just do this. Or better create a new category for paid posts.
Tell me will you want to do paid posts now.
@Renie: do they really pay that much of money for blogging. get me some of those projects man. I am ready to do.
