According to Next Web, the new Twitter feature to download your history is now active for some people.
It's not active yet for my account, but I'd still like to learn more about the format. So if it's available for your account, please consider sharing your archive with us techies so we can have a look inside.
If you have an archive, you can upload it somewhere or email it to dave dot winer at gmail dot com and I'll upload it so everyone can have a look. Thanks!
Update: Thanks to Navjot Singh, we now have an archive to explore.
I just checked and it's not active for my account either. I do want it, though.
I wonder why Twitter wouldn't also want an archival view, plus an archival search, rather than just a download option. Why should tweets be snow on the water, or the life tweets depict just a brief LIFO buffer? Could be they're thinking bigger here, but it's hard to tell.
Or maybe what this says is that, if archiving matters to people, then maybe it's a personal thing. If so, and the demand is there, maybe theres a market for software to do one's own archiving.
