I have been observing that top bloggers like JohnChow are luring and fooling newbies by inducing them to buy crappy products like MillionEuroWIKI? http://www.gnaka.com/general/the-chows-cows-desperate-to-milk-you Do you think, you hurt your reputation as a blogger by promoting crappy products to your loyal readers?
You can definetely hurt your reputation although the odd blatant plug isnt too bad (hey we all gotta eat right). At any rate I would never refer people to a product I had no faith in, maybe JohnChow really believes there is benefit for people in MillionEuroWiki.
Whether MillionEuroWIKI is crap or not, time will tell. Always evaluate every single product or program with a set of criteria and you cannot go wrong.
