LJ / Dreamwidth

I gather there is an LJ > Dreamwidth migration afoot, and it has something to do with Russia and with some LJ users being banned, but I don't know the details. If there's a search term or a post somewhere explaining it, I'd like to know about it.

I consider my primary home to be Dreamwidth, but I'm going to continue crossposting to LJ for now.

If you have an opinion about that, I'd be interested to hear it. Comments are screened but I will unscreen your comment if you say it's OK to do so.

[ETA] Here is a non-LJ/DW link that has more info:
