If you download your Twitter archive it arrives wrapped as a static HTML page, which is not very useful for doing anything with, and worse: it requires the original account to be still active to do useful things like enlarge the images since they use t.co links.
So here's a Python script to convert a Twitter archive to markdown or other formats: https://github.com/timhutton/twitter-archive-parser
Now you can archive your tweets in any way you want.
@timhutton definitely going to take a look at that when my Twitter archive is available (assuming the site stays up long enough to get it - my archive will be pretty massive)
Curious if you know of any services that help you search/query/analyze your Twitter archives? Do anything useful with them (like expose them if you choose to do that in an archival form somewhere?)
