I know this seems a little odd to write -- if you have friends, you should always be in touch with them, right? -- but after a Christmas of filling out cards and saying, "man, I haven't talked to this person in forever," I've turned to RTM for help.
I've got a list of those friends, and a reminder to "Say hi to" or "Send an email to" each of them. To make sure it's not a one-off, I've made it a recurring task for some random period of time: 57 days, 126 days, 245 days, etc. I sure expect to talk with them before that, but now I have a regular reminder if life gets busy... and they don't get in the mindframe of, "It's the 1st of the month, I should get another email today."
