as Nuero said, i shoot at whatever aperture that gives me the required depth of field that the situation calls for.

that being said, i almost never shoot "wide open" as i prefer to stop down at least 2/3rds+ stops to maximize sharpness when i'm shooting for that "bokeh look".

Depends on lens and subject, but to generalize:

16-35 2.8L II .... usually between 5.6 and 16. Sometimes 22 for DOF, sometimes 2.8 in really low light
24- 105 .... usuall f/4 to 5.6. Occasionally 16-22 for landscape deep DOF
28 2.8 IS .... usually 2.8 - 4
40 2.8 .... hardly ever use it
50 1.4   usually f/2 ... sometimes 5.6 - 11 for incredible sharpness
70-200 2.8 IS II .... usually 2.8. Occasionally 4- 5.6 for easier in focus video

It depends. 
I normally use a 24-70 II.  I shoot at f/2.8 90% of the time.  The times I stop down is when I don't want such a shallow depth of field and when the light is too much to get a nice picture.
Canon 5D Mark III and Canon 60D; EF-S 10-22; EF 70-200 f/4L IS; EF 24-70 f/2.8L II; 580EX II.  Soon to add: 50 1.2L, 135 f/2L, 8-15L

Hi - I shoot mostly landscapes, cityscapes and still lifes and the aperture I use depends on many factors and on the lens I use:

¤ at night I mostly use really fast glass (24LII/1.4, 35/2.0IS and 85LII/1.2) at their widest aperture in order to prevent motion blur and limit ISOs. That's very handy in the many cases I can't set-up a tripod (in museums, on the streets, etc...), and I usually work around the "issue" of shallow DoF by using the most appropriate focal length and doing multi exposures (if I really need a long DoF that is).

¤ in broad daylight and/or when I can use a tripod, I use a wider selection of lenses from the 8-15L/4 to the 70-300L/3.5-5.6IS, which I usually stop down by one to three stops in order to optimize sharpness. If I need a better subject isolation then I often open the lens to its widest aperture. For landscape I usually stop down further in order to increase the DoF but I avoid going beyond f/13 to prevent the loss of sharpness due to diffraction.

No, because it rarely gives me the dof that I require. For the landscape panoramic shots I'm always at f8 to f11. Don't want to go smaller than f11 due to resolution drop off.

When using faster lenses and wanting to isolate the subject I'd only be fully open if a reasonable distance from subject. If very close then even f4 gives a very shallow DoF depending on focal length. I suppose the lenses that would get used most by myself at a wider aperture are faster wide angles where even close to the subject you've got reasonable dof at 2.8.

Speaking from a personal point of view I see a lot of ultra shallow depth of field pictures that would have been better if they had a little deeper plane of focus.

40 2.8 - usually 2.8-5.6
60 2.8 - 2.8-11
200 2.8 L II - 3.2-5.6, with 1.4 extender - 5.0-7.1
EF-M 22/2 - 2.0-4.0
EF-M 18-55 IS STM - 5.6-8.0

If I want to shot wide open usually 1/3 stop down is good for even for high quality primes.

Yes I shoot my 24L II at f1.4 all the time, either f1.4 for close up portaits or f8 for landscapes.

70-200 II, yup, f2.8 all the time.

S50 would need to be stopped down to 1.8 to give good sharpness / contrast.

16-35 II is the 'dog' in my line up and when doing landscape I will use f11 and manual focus most of the time. Open up and the corner makes you go "ouch!"

I shoot at the aperture I need for the DoF I want, with concessions sometimes made to get a high enough shutter speed/low enough ISO.  Good lenses mean I'm not afraid to shoot wide open when I need to, and with the exception of my fast holy trinity of primes, I do shoot wide open a fair bit of time.

+1 for me too
Yes, I agree with my teacher Mr. neuroanatomist that " I shoot at the aperture I need for the DoF I want".

Yes, Depend on our Need and the Purpose of that single Photo. Yes, If I want to make the Background  to support the main subject---Not Interfere , I just Open the F. Stop wide like 1.2 of 85 mm, MK II, Photos # #2 and # 3 ( The DOF will be very super Shallow)----But  If I want to keep the total Sharp of subject such as human/ Model, I just use 2-3 Step down Such as 1.8 or 2.8 , Photo # 1, for to see what in the back ground  just for the story teller. If I shoot the Scenery View, I try to use 8.0 up to 10.0 for the most of Sharp of DOF.,  If I want to get the star effected( with out Have the Stars filter in that time ), of shoot direct to the sun  between the tree branch, I will set the F. Stop up to 16.0 or the smallest FD. Stop of that Lens.----Big BUT, If we use the small  F. Stop  beyond 11.0, We will suffer of Lens Diffraction, "Diffraction is a loss of sharpness or resolution caused by photographing with small f/stops"

Yes, Just the Theory, But I do not care, I will set the F. Stop as I need, Shoot 3-5 Photos  at Difference F. Stop, And Select  the Photos in the Big LCD. Computer screen.
Nice to talk to you, Sir.

PS/. Photo # 1 = F = 2.8 ( 70-200  MK I)
       Photo # 2. # 3 = F = 1.2 ( 85 mm  MK II)
       Photo # 4  F= 11.0 ( 100 MM L IS  Macro)

The Sample of Difference F. Stop.
Photos # 1, # 2, = at F 13.0, Very Shallow  DOF for Canon EF 600 MM. at Long Distant.
But Photo # 3, For 11 mm Lens at F = 5.0, Very deep DOF.
Enjoy.

I usually shoot about 2 stops closed down.  I buy a 1.4 lens not to shoot at 1.4 but to shoot at 2.8 for sharpness.

The only time I shoot wide open is when I have no other choice to get the picture or when I specifically want limited DoF. 
I shoot with a Camera Obscura with an optical device attached that refracts and transmits light
