I've been getting a daily dose of productivity pr0n from Lifehacker for years. Taken altogether, the tidbits I've picked up there have saved me at least a month of time. Most recently, the the use of Simplenote  for plain text capture and synchronization across machines and handheld devices. 

Now they've seen fit to use one of my pieces, "A Defense of Writing Longhand." Check out that byline! I'm really quite proud of this.
