I promise you, I have searched high and low for one. Result so far? Rien, nothing, bugger all. You can either tick your areas of interest and wait for an advertiser to pass by and ask nicely if you wouldn't mine writing an article for a certain price. If the price is too low, you can tell him to get knotted or suggest a price more in keeping with your ego, blog affluence, financial aspirations or negotiating acumen. That is the ebuzzing direct concept, the equivalent of headhunting.
Alternatively, you can search out products of interest and submit a request to write about it. That is ebuzzing network, the equivalent of applying for a job.
Being a lazy sod, I'm rather inclined to prefer ebuzzing direct, and sit on my butt until someone falls from the sky. The thought of wanting to write a blog post with the sole intention of earning some dosh is slightly not my thing, but I'm quite happy to react to being approached. Commerce is so tricky, is it not? One really does not want to risk selling one's blogging soul to the advertising devil.I think ebuzzing avoids blatant commercial exploitation by getting people to write about things they would anyway, but get paid for it as well.
That, my blogging confrères, is cool!
