From the video you can tell that it went a very long time before they started with the Evacuation C-list. If they performed it at all. From pictures you can see that the GND spoilers are still UP after the PAX had left, which indicates that they didn't perform the Evacuation C-list OR they performed it unsatisfactory as the second item on that list is SpeedBrake lever DOWN, a Captain's item.
You can also see that the flaps isn't in 40 degs, which is the position the FO should place them according to the same Evacuation C-list.
Maybe they had no hydraulics available.

Do they start the APU before landing?

Were the engines shut down first before stowing/positioning flaps and spoilers?

I don't know what SOPs are for a nose wheel collapse but shutting engines down may be high up the list.

I can't find a single instance of a down and locked B737 nosegear collapsing on a normal landing without first striking something. Is there one?

Second, the iPad video seems to show a runway excursion. If that's the case, did the nosegear fail after the excursion, which might have been caused by something else, as suggested by Nigel above?

There´s another video on Flightglobal which seems to indicate there was a wheel rolling on the ground behind the aircraft:

Wow, the wheel travelled a long way, a good distance of it seemingly perpendicular to its original direction.

More likely the Captain decide there was a risk of fire where the fuselage had scraped down the runway and chose to use only the aft slides.
Captain doesn't decide that.

Here's another nose gear collapse. OAK six years ago:

Southwest flight's gear collapses on landing at Oakland airport - SFGate

Was not a "normal" landing as they had gear/hydraulic issues prior to the landing but at some point they had "three green" - indication of 3 down and locked landing gear in the cockpit - prior to landing. Nose then collapsed after touchdown.

If anyone thinks the crew in LGA had anything other than three green prior to landing they are crazy. The nose gear may very well not have been down. But I would say with 100% certainty that they were indicating down and locked in the cockpit. If not, no way they land at LGA.

Legarbage airport always got my attention on landing. A bad karma day and a hard landing most likely.

Actually, no. He might give the order to evacuate, but no American carrier I k ow of has a Captain dictating which doors to use. That's a decision our FAs make.

Actually, that is a decision that a passenger is capable of making. Also, I would dictate which doors to use during an evacuation, if I felt the need to.

Apparently your knowledge of all American carriers isn't quite as exhaustive as you thought.

The Captain will order the evacuation including a command that specifies the exits to be used. For example "All Exits" or "Left Side Only" etc. The flight deck crew may have knowledge of a threat or potential threat that the Flight attendants haven't been made aware of. Obviously, the Flight Attendants will then assess their exits.

This American carrier no longer restricts the exits the cabin crew will use...

Must be a malfunction to landing gear lights, as it reported the landing gear down and locked when it reality it's probably down but not locked, and as a result when the plane landed the front landing gear snap off.

Had there been an indicator light issue, the crew would of definitely try to fix it first (the CVR will tell if that is the case), and even if they are low on fuel, the flight crew will notify ATC that they need assistance because of abnormality with landing gear indicator. So far, no report that ATC received such request.

I keep hearing that the gear rotated backwards and was driven up into the electrical bay.

Is that a direction that coincides with an unlocked gear or a hard nose down on a locked gear?

I still can't figure out why the wheel itself came off? I suppose there might even be the possibility that the gear was down and locked and that the wheel was the first thing that let go allowing the strut itself to dig in, but that doesn't match my visuals of other aircraft landings where the nose wheel just swivels away in a shower of sparks but doesn't collapse.

Pictures floating around of the nose gear up in the EE bay with the axle broken which is why the wheel was following the airplane.

Looking like a high sink rate landing at least maybe a wheel barrow.

You can assume for what that is worth, but short of a downburst looks like lack of a flair trying to hit the markers on a short runway.

Carrier?

Why would the Captain dictate specific exits only to have the FAs make the call in the end.

Our FOM has the Captain making the evacuate command a d that's it.

Gear, meet avionics. Looks like it hit pretty hard.

The video of the flair and landing has surfaced. The video was taken from an over wing seat looking forward. It did appear to be quite a 'firm' arrival. Whether the front gear failed immediately is hard to tell.... The amateur film maker had his phone knocked out of his hand at touchdown.

Regarding this little gem ....... I'm speechless:
