Seeing more "cake days" pop up lately, it seems we're approaching (or in) the 1 yr anniversary of the Reddit migration.
It's kinda sweet actually that we all get this reminder of it with the pickup in "cakedays".
It reminds of my seeing the wave happen. I was on lemmy before the migration (not a flex, I joined mastodon in the twitter migration and explored the other fediverse platforms around looking for a reddit/forum alternative) ... and followed a bunch of communities over on my mastodon account. Early last year many of these communities were fairly quiet (or at least quieter than now) and so I didn't really see any of them in my mastodon feed. I'd actually forgotten that I'd followed them. I'd heard word about the API stuff over on Reddit, but I knew something was happening when I started seeing more and more posts in my masto feed that confused me ... it wasn't clear where they were coming from. Double checking I'd see that they came from lemmy communities I'd forgotten about ... and I realised I was seeing lemmy literally come alive!
All these cakedays are kinda the same thing ... a sort of internet equivalent of a weather event or season.
