It appears to have only been used when communication here on the forum was not possible. These days, however, we get very few cases of downtimes and the forum is less susceptible to DoS attacks. If the forum is accessible, there is no need to use an external platform to communicate to get community.
It's however good to note and follow, in case it could become active in the future for some reasons.
Everything moves on its own on Bitcointalk and are not really mention-worthy, except if it involves its own development (e.g. forum software).
But then, the owner (presumably theymos) didn't post the anniversary design contest so I guess it's inactive until he hires some social media manager to take over.
