If someone discover how to do something in a retard way and post it on FB, it does not mean you were wrong ! Using that method will eventually burn yourself with hot water !
Also the drainage holes are pointless in the middle as lowest point where the water will run will be at the edge. You can achieve the same by holding the lid on the pot slightly ajar.
This would: 1) Be super awkward and full of poorly distributed weight, 2) most likely end up burning you and having you drop your grip and the whole mess dumping into the sink, 3) Melt the plastic colander where it touched the metal pot. If you can't manage to use a colander just purchase a pot with a strainer lid.
There are half moon strainers you can use if you don't want your noodles to leave the pot.
