A little bit about my twitter archiving approach
I've had my account since 2007. Since then, I've archived and then mass erased my tweets multiple times.
It's been a few years since the last purge, and since then I've increasingly relied on using twitter to document things I've been working on, and going back to those threads for reference.
I want to make sure I still have access to that info. The new twitter archive is pretty good for that.
