No disagreement from me. I personally don't see how the progress of a backend could be visible either.
But as I have said, I have not seen any visible signs
of progress for a long time, and by that I mean even just things like Tsuki mentioning anything regarding it. (There was indeed an instance of him doing that when it was relevant to our conversation, but that was months ago, and that conversation was even in private) He may be unable to do even just that for reasons and I will not blame him for it, but in any case I wouldn't get my hopes up about it happening anytime soon., and to repeat myself again I advise that no one else does as well, lest you get impatient and start spamming the boards about it.
That also reminds me. During the older (post hiatus) site's development, Tsuki did actually from time to time say things like "the new site is now something% complete!", that could've been him shitposting but they kind of aligned with the site's opening and certain other events so I doubt that. Now, I'm not asking for a percentage, or honestly, anything right now. All I'm saying is, I (and probably most people here) have not seen anything indicating that the site is going to return soon, and thus have no reason to believe that it is the case.
