The history on de-wicking/de-bridging or de-bridging in a less snidely fashion
Great steps have been taken in making the wicks burn resistant. It wasn't so once upon a time, and in some instances are still floating around.
Folks were burning their wicks getting a foul taste and wanted to remove the wick. The only way to do this was to de-bridge the atty (510s, 801s, 901s etc...) and wasn't necessary for exposed bridge atties e.g the 306. BTW de-wicking is the only cure for a burnt wick, which normally is associated with over vaping an atty, or vaping it too dry. Cleaning them will not rid the burnt taste and dry burning will exacerbate the problem.
The wick made up of proper material not only carries fluid to the coil, it also cools the coil = greater atty life.
The rationale when folks moved away from carts was why is the bridge necessary? I drip and want to get the juice where it needs to go - on the coil. The truth is it will get there in the "proper" amount with the bridge and mesh intact. Look at the genesis atty which uses SS mesh as a wick. From the SS mesh (the main wick) it delivers liquid via two tiny holes to the cup. A properly filled cup whether dripped or capillary fed will ensure the coil is getting the correct amount of liquid to be vaporized.
The truth of the matter is when most folks think that the drop needs to be dripped on the bridge is misleading. The bridge placed the mesh against the batting in the cart and wicked the fluid to the cup. But the main reservoir was the mesh surrounding the cup. Therefore dripping into this mass is where the drops need to go, certain drip tips are designed to do this.
Removing the bridge will leave a space (the thickness and width of the bridge) between the cup and the mesh making the atty more prone to leaking, whilst leaving the bridge in place will permit a certain amount of wicking away from the coil for optimum vaporization.
A bridgeless atty is also more prone to flooding and leaking, for previously mentioned points. It is a delicate balance between optimal and partially flooded or flooded. Vaping through a flooded or partially flooded atomizer in most instances is worse than vaping a dry atty (for the atty that is).
Most atties these days come with fire resistant wicks and hence their removal is pointless, whether dripping or bottom fed. The burnt taste most folks experience is associated with the spent liquid in the atty rather than a burnt wick. This liquid is incapable of volatilizing any more and should be blown out, or it will caramelize in the mesh and on the coil creating blockage in the mesh, creates carbon on the coil at an accelerated rate and a foul taste. Regardless atties are a semi disposable item with which we keep around for far too long past their proper functioning date, we all do it.
Is there anything else you would like to know from this condescending individual?

In the end it is whatever floats your boat and keeps you off the stinkies that is important. At times you will hear things that you are not prepared or unwilling to hear, OTOH I don't blow sunshine.
