Ask HN: Software to manage a jobhunt?

When you're on a jobhunt, there's a lot to keep track of:

  - Job ads
  - Notes on companies
  - Contacts
  - Who you've contacted, when, and about what
  - When you've sent out your resume and to whom
  - Interview schedules
  - Followup schedules (who and when to call back
    or send thank-you notes to)

What software do you use to keep track of it all?

Do you use a bunch of plain text files? Do you break out the old spreadsheet? JibberJobber? Something else?
