comment How can rope/cordage be packed to minimize tangles?
Borrowing a little intuition from knot theory, if you coil from both ends at once (like the butterfly/backpacker coil) then any twisting/torque you put in the rope gets canceled by the opposite torque in the other end, You are less likely to get twisting (which leads to knots and wadded mess) if you coil both ends together. The disadvantage is that you need to flake it as it won't just spool out.

comment What is the difference between men's and women's hiking boots?
I think the wideness factor is the real reason, Although it probably doesn't apply to hiking boots as much as just regular shoes(I've never seen a "wide" size for men's shoes, women's shoes have that designation though). Obviously though, as long as it fits and is comfortable its really all about sizing convenience.

comment FiveFingers or hiking boots?
If someone was completely used to wearing five fingers the lack of ankle support shouldn't be a big deal even with a heavy pack. I'd say the biggest concern (for someone who is completely used to five fingers) is most definitely the warmth factor and, depending on the terrain, traction.

comment Preventing cross-loading on belay carabiners
While cross loading a biner is usually bad news bears, the type of forces and the typical magnitudes that are exerted on the belay biner make it not that big of a deal. Just make sure its stays locked, and make sure its a munter biner and not a standard one, and you should be fine. This is especially true for top-rope belaying (assuming you are top roping in the gym).

comment What do I do to prevent and treat frostbite?
+1 for stomach warming, an old school mountaineering technique that breeds camaraderie and can save a finger or toe.

comment What does it mean to cross load a carabiner?
Even more dangerous than cross loading is nose hooking, a nose hooked biner can fail under body weight forces blackdiamondequipment.com/en-us/journal/climb//…
