I am not the biggest fan of christmas shopping guides. They always feel like such a huge marketing ploy. And when they are not busy being a marketing ploy I usually find them hard to relate to anyone I am buying gifts for. This however is a mark of how insanely difficult my friends and family are to buy for. They all seem to fall in the category of "those who have everything, and extremely expensive taste". Unhelpful.
But if you are lucky enough to have a few easy people to buy for, or perhaps a few Ruby-enthusiasts (like myself), check out this great gift guide.
