Since I'm seeing a new wave of people saying they plan to leave Twitter, you may like my browser tool that takes the zip file of your Twitter export and returns a zip file of a web site that lets people browse and search your tweets. You can just upload the files wherever you normally host html and it'll work just fine.

@darius do you know of anything similar for a reddit archive?
