As a dull and gray developer geek I would call it a frontend :)

But when I try real hard to come up with a great name then I would call it ....

Triglav

pronounced tɾiːɡlau̯

meaning Three Heads (Tri Glav)

Three reasons:

Triglav is a Slavic god of Prophecy and Sooth-Saying - prophecy and soothsaying go well with social media / community blockchain platform, I think :)

God Triglav also connects the past, present and future on one hand and underworld, earthly world and heaven on the other hand.
Triglav is also the name of the highest mountain in Slovenia. Yes, it has three peaks :)
Triglav was once a computer desktop model with three different CPUs and operating systems inside the same box. Amazing concept and well before its time.

Do you see any parallels? I do!
