I use them only for last minute tickets which would cost an arm or a leg. You should be aware that a UA 1K has NO blackout dates and no advance purchase restrictions when it comes to using miles. So I can use the miles on a whim's notice as I please.
So far I've used them to fly myself and friends around cross country a number of times. My good 1K buddies use them to go catch the US Open at NY, see new family members in FL, etc...
I have also donated some to help a local acquaintance book a last minute flight to see a dying family member, as well as donated some miles...
