Travis,
Might I respectfully note a couple "nits" with the info you gave.
While I don't disagree with the practice of pushing a drop or a few drops of ink from the nib, I'm not sure I agree with the fact that this action is what "primes the nib", nor is it really as necessary with c/c (cartridge/converter) filling pens as it used to be, (or still is) with other filling systems such as rubber or silicone sacs.
When you dip the nib down into the bottle of ink, really, you just "primed the nib". A single dip into the ink will probably load the nib, feed and combs with enough ink to write a half page or more worth of text with no additional ink sucked up into the converter.
With sac filling pens the warmth from your hand or body if the pen is in a pocket, once it warms through the pen, can be enough to warm the ink inside, expanding it out of the sac, feed, nib, and onto your paper or shirt. By pushing a few drops out of a sac filler FP you create a small but usually sufficient air space in the sac for the warmed ink to expand into instead of going in unwanted places out the nib.
I don't think that converters are imune to this phenomenon. The same thing can happen with them, but their design makes it a little harder for the average FP user to make it happen.
Screw the converter plunger all wth way to the bottom...what do you see...it really doesn't go all the way to the bottom. So even if the ink begins sucking up immediately, you will have a small amount of air pre loaded into the converter from that gap between the bottom of the converter and the plunger. It is possible to completely fill a converter with absolutely no air gaps, but it takes a conscious effort and usually several tries to do it successfully, (trust me, I'v tried, and you don't come out of the experience with clean hands. [

As to emptying for storage, with a reasonably good fitting cap, I'm not sure I'd worry about it unless the pen would sit unused for several months or more. It certainly wouldn't hurt anything to empty the ink more often, but unless you rinse and flush the nib, feed and reservoir you still have ink sitting there that could dry just the same.
YMMV, contrasting opinions welcomed, etc, etc.... [
