Making a kilometer blurry
Yeah, the watermark is pretty crazy. He's gotten the best photos of me by far, so I have bought from him a couple times over the years. There was only one photographer shooting my solo break in the rain, and it wasn't some dadwithacamera 
You will see more and more pro photographers protecting their work more aggressively as time goes on. If you buy it, there's no watermark. If you want something to post up on FB, choose a lesser photo from an amateur who doesn't protect his images.
Regarding the position, I've never been able to get my back to curve on the road position. It does a bit more in the TT position. I've also done threshold tests on the hoods, tops, and drops, and seen very little variance. Huge difference in aero testing though.

Yes, there are many ways to get aero, with various tradeoffs. Note that you actually get lower when bending at the hips than bending in the middle of your torso. That comes with tradeoffs as well.
Notice how my shoulders are at the same height as my hips, where yours are 6-8" higher than your hips. Your sternum ends up at the same angle as mine, but my sternum is relatively lower, so my belly is catching less air. I'm actually another 3"-4" lower than this in the drops when arms are parallel, and can ride at this same angle in the drops with arms less bent:

In all honesty I was probably a tad lower there than usual because I saw the photog as I passed. Typically would be closer to waterrockets in shoulder-to-hip drop while riding in the drops.

Aerodynamics are hugely interactive. Take the same person, change their aero bar extension and the best helmet suddenly drops to 3rd.
I've probably got more testing hours here than anybody but Nate and I've sat with guys who get paid lots of money to work with pro teams in this field and we made guesses as to which set up would be faster. Too often we come away shaking our heads going WTF?

This. They are useful in that they are starting points. After that, you test. Then test some more.

Even if you're someone like me who just buys whatever helmet is on sale and looks decent, rides the same equipment for years, testing can still pay off. After doing the cheap aero testing (linked above) with a teammate, I learned that deep in the drops, I had better aerodynamics than IAB. That has impacted my position for pulling in breaks, as I would go IAB about 50% of the time. Now I know that I need to suck it up and get all the way down in the drops (power doesn't suffer in a 1' pull). IAB is a close 2nd, so for solo stuff it's a lot more comfortable, but I'll go back into the drops for gusty/head winds or descents.

Not that I have seen. They are lighter than stainless and can roll better mainly due to the light lube and low friction seals.

Most (not all) ceramic bearings take significantly more maintenance than steel bearings, especially in wet, gritty conditions.
To the extent that up here, if a racer wants to use them and isn't the sort to lube/maintain/check bearings after a couple wet rides (8 months of the year up here), I advise against it.
They pit & breakdown quickly enough compared to steel that in my experience, they aren't worth it.
ymmv

brake/tire clearance question. just got some HED jets. rims are 23mm wide, and i'm running 25mm tires. i can get the brakes (shimano) wide enough, but when i do, the front tire actually rubs the center of the arm of the front brake (since the arm drops lower as cable tension decreases and the brakes open wider). there's one perfectly adjusted spot where everything works, but there's pretty much zero room for error.
are there any brakes that have more clearance? again, the issue is vertical tire clearance, not horizontal rim width clearance (although i guess they seem to be related).
edit: and yes, i realize one solution is just to use 23mm tires.
