So, where are we now with LN in bitcoin? Has it been abandoned and forgotten?
your comment proves that your source is social media, and you are correct the "hype" about Lightning Network on social media like bitcointalk and reddit has died because the fees have come down. (by the way this has nothing to do with litecoin! not that many were using LTC itself before LN)
But I don't deny it. Wasn't that what I made clear in OP? There is not much talk about Lightning Network on "social media like bitcointalk" nowadays, yeah. That's why I decided to ask this question here. Of course, I could have looked through all the sources you provided myself (and use Google too), but I thought the current standing and situation with LN might be of interest to other people as well.
Well, to tell the truth, I'm not really fascinated when someone uses phrases like "development is still ongoing as strong as [never] before". Most of the time, it pretty much means that the real development has stalled. For us, people who don't follow such questions very closely, "strong development" means introduction of respective features in major apps, even if only as beta versions and pre-releases.
So, is there any change we are going to see LN make its way into major wallets any time soon?
