"The photos will either include an ad overlay on part of the image, or embedded advertising that pops up when a Web user runs a cursor over the picture."
An example, based on what's at the PicApp blog.
Okay, say I really, really, really need a piece of stock art that I can't get anywhere else, and I'll put up with an embedded ad. What powers Corbis' embedded advertising? Flash. Yes, why embed a mere photo in your page, when you can have a Flash widget that looks like a photo, but also serves up a text ad?
Look, unlike some steal anything/share everything folks, I do believe in some theoretical way for content creators to maintain some level of control over their content or even get paid for the use of it (even if I Creative Commons license most of my own photos). But this is just crap.
Good luck with that, Corbis.
Oh, and they also mention potential revenue share, based on clicks to the photo. That leads to item #2...
...from Read/WriteWeb, There's No Money In The Long Tail of the Blogosphere, which smacks down some of the Web 2.0 long-tail sloganeering and says that, while long-tail content aggregation companies may be able to make money, don't expect long-tail content providers (regular folk) to do so. In other words:
"You can make money on the long tail but not in the long tail."
Sounds about right. Hey, apparently (well, according to a throwaway line in Heinlein's The Rolling Stones) the fortunes to be made during the California Gold Rush didn't come from the gold-rushing prospectors, but rather to the merchants who provided products and services to them.
And for all those get-rich-quick bloggers -- unless you find a niche (and you're a first-mover, at that), don't expect to make any money. (I used to cover my hosting nut with Google Adsense ads -- mostly from clicks on my platonic friends pages -- though that hasn't happened for a while.)
But wait -- aren't we in this for ourselves? At the very minimum, aren't we participating in the broader sphere o' blogs, staking out a spot in the global communication? Sure we are. But blogging is time and time is money. I barely pulled a C in econ, but that sounds like an opportunity cost to me -- if I spend 10, 20, or whatever hours a week blogging, when I could be using that time to earn money, at what point does it stop making economic sense to blog (or at least to cut back)? How much is ego-stroking or a creative outlet worth?
