CDs have been making a slow comeback for the past year or two, and global CD sales actually went up last year for the first time in over a decade. If it's anything like the vinyl or cassette resurgence, I imagine it won't be too difficult to find places that sell CDs in a few years.
I mostly stuck to a small circle of communities on Reddit, and while the quality of content has stayed about the same, the frequency of posts has dropped notably in most of them.
The one exception is /r/iiiiiiitttttttttttt/, which is supposed to be for IT memes and funny interactions with users. Since the blackout started, that sub has gradually devolved into reposts of years old memes (not even IT specific memes, just anything tech related) and text posts asking random computer questions, which was previously banned.
Someone (presumably at Reddit, but there's no hard proof of that), has recently begun using a large number of dummy accounts and what appears to be ChatGPT to post pro-admin, anti-protest comments across the site, and give them a lot of upvotes. Someone figured this out and posed evidence of it to /r/programming. Shortly after that thread reached the top of /r/programming, the subreddit was abruptly closed by the site admins, which is extremely suspect to say the least.
It's for Mastodon compatibility. Articles are like Reddit posts and microblogs are like tweets. You can post either from Kbin. Your articles will show up as community posts on Lemmy, and your microblogs will show up as toots on Mastodon.
