The administrator gave up
No longer pursuing Epochtalk, I think it's a good choice, the name is weird, it might not able to attract as many as Bitcointalk name.
I think it was just the name of the software, like SMF is the name of the software that powers the current version of the forum. It was never intended to be a replacement for the Bitcointalk name.
And it was a terrible decision. After all the time and money poured into that failed project, there is no way to spin it as anything other than a complete waste. It was a bad choice by every possible metric.
