Really? I thought he still had some sort of serious pull as far as the forum is concerned (though I'll admit I don't keep a close eye on forum politics). How long has it been since Cøbra hasn't been "associated" with bitcointalk?
Well, I'm not talking about influence, they can remain friends, it's their own business. Their paths finally parted ways a few years ago, theymos is not related to bitcoin.org and Cøbra is not related to bitcointalk.ogr. That's why I assumed theymos is the only owner of the twitter account (since it's a bitcointalk asset).
To answer The Pharmacist's question directly, theymos made the update to domain names on April this year, so safe to assume that was when they both cut connection from the other website after years of minimal involvement from both parties.
...
However, Cøbra has never had much involvement in bitcointalk.org's operation, and I haven't involved myself in bitcoin.org for a couple of years, so the linkage between the two no longer really made made any sense. Therefore, we decided to separate the domains: I no longer have any access to the bitcoin.org domain name, and Cøbra no longer has any access to the bitcointalk.org domain name. The two sites should be viewed as totally separate, which in practice they have been for years.
...
Because I clearly said twitter would be used for posting short stats or posting screenshots, and not for writing long posts.
I don't think forum stats have been of much importance to theymos, and cherry picking posts to screenshot on an official social media account may not be a good idea from my PoV.
This may however be a good pet project for someone who is genuinely interested in promoting the forum on social platforms as there's a growing interest in Bitcoin on these platforms like Twitter, and no restriction to create an unofficial account, if you find someone to organize it with, you are free to do that.
