twitter is a happy place

SYK!

hell no!

Thanks to the power of the fediverse and following the right people a skillfull fellow mastodon dropped the nitter bomb on me a couple of days ago.

Of course I asked first what it is, then both replied that it's a front end to the twitter api (yes to me only twitter existed till it was murdered by little elon) which never reveals you, meaning I can not only access my old accounts which I have downloaded (of course thousands of tweets!) conveniently as it is frozen in time. I have the imagery in front of me, instead of that large JSON pack

deleting twitter accounts will not erase the data automagically{servers never erase!})

I now thank the people who gave me another TIL
