Is it correct practice to place a comma after a conjunction (that begins the sentence it's in)?
So, Nathan draws the curtains to see what's beyond his dungeon.
But, I don't see the point in trying so hard!
I have often seen commas being used in such instances. But, a quick google search seems to imply it's wrong.
One of the most frequent errors in comma usage is the placement of a comma after a coordinating conjunction. We cannot say that the comma will always come before the conjunction and never after, but it would be a rare event, indeed, that we need to follow a coordinating conjunction with a comma. When speaking, we do sometimes pause after the little conjunction, but there is seldom a good reason to put a comma there.

Two specific situations call for the use of a comma before "and." The first is created when we have three or more items in a series. [...] The second situation occurs when "and" is being used to coordinate two independent clauses. [...] The use of the comma would also apply when any of the seven coordinating conjunctions (and, but, or, nor, for, so, yet) join two independent clauses.

The sources of both the excerpts seem reliable enough. This puts me in doubt.
Many people erroneously believe that beginning a sentence with any coordinating conjunction (especially, and and but) is wrong in the first place. I suppose that's why this construction was not considered in the texts above.
The more I think about this, the more I'm convinced that this is probably a grammar myth.
