I've been curious about this service too, so I went ahead and joined up to see how it worked. I wrote a posting on my Blogger account about an experience I had a while back at McDonald's, to meet the criteria of a specific promotion. I started out by going to the CREAMaid site and seeing this:

Okay, I can write about McDonald's. I clicked on that and up popped their nifty widget:

At the bottom of the widget, I clicked on "Click Here to Participate" and here's what I learned:

Now I switched over to my Blogger account and wrote a new blog entry that fit the criteria. Following along with the steps noted in the widget, I then entered my email address (though it was darn confusing that it said "you're done with your blog posting, now enter your address for payment" even though I hadn't yet been able to discover how to add the all-important CREAMaid widget to my posting. No worries, turns out that they just have a few steps out of order.

Next up I have to indicate what kind of blog tool or site I'm using:

Even though I'm blogging about McDonald's on Blogger, I'll opt for the second choice because the widget - as you'll see in a minute - is far less invasive. It shows me a small text box right in the widget itself that contains the necessary code to include in my blog entry to get credit with their network:

and the source in that tiny box? Here ya go:

The end result is in the middle of the blog entry itself:

Quite inoffensive, actually. Much less invasive than the fancy widget.

Not more than a few minutes later I received an email message from CREAMaid:

Hmmm... I saw this message on the 13th of October and it references clearing things up by the 7th. So maybe I won't get paid, and maybe I will...

So that's my experience. Should you do it? Well, I don't know that I would have written about McDonald's without the desire to tap into this offer, but at least there was no requirement to write something positive and $10 is a fair payout compared to the $0.03/click sort of revenue stream most folk see from Google AdSense and the like.

On the other hand, there's no requirement or even recommendation that you should disclose that your post is sponsored or influenced by the ad campaign, and that's a serious problem in my book. You should make your own conclusions about the ethics of having this on your blog, however.
