I hadn't come across this blog before, but the breathless prose in this drivel beggars belief (emphasis mine): "As a matter of fact, whatever you happen to be looking for, I bet you'll be spell-bound with the search results."
If that's not over the top enough, there's this: "Pixmac's lofty potential is split in two. Part can be found in the credit-based Subscription Collection (2.5 million and it's safe to say that these are the most cherished items), ..."
Even in the "good old days" I don't believe any agency treated our content like a cherished item! This type of pseudo article is like the fake editorial in the advertising sections newspapers used to publish - all it does is erode any credibility the organization might have had for any words they weren't paid to say.
I don't mind ads (I happily ignore them) but I despise attempts to pass them off as genuine recommendations. On the other hand, having excluded all the major agencies and included only old-news also-rans, I can't imagine anyone will pay much attention.
