I'm a mix of OK and not-OK.
The good: I'm excited with Xmas + New Years' Eve. It's just family but I always get hyped up. Learning how to paint oil on canvas. Got nice gifts for my family, "nice" not as "expensive" but as "things that they'll enjoy".
The bad: lots of things to do. Juggling the will of five people and two cats for the festivities, as I'm the one cooking most of it. (Yes, the cats will get treats. Yoghurt for one, shredded chicken breast for another.) Work is also extra hard those days.
The ugly: I hate summer. Insect thinks that my desk is a love hotel, my feet get swollen, 13:00 and I turn into mush, my cats get more nocturnal so late night/early morning they're "MEOW, MEOW" = "stop sleeping and play with me, stupid human". At a certain point in my life I seriously considered buying a house in the Alps so I didn't need to deal with summers any more.
Most people don't even know what's a proprietary image format. From their PoV it would be "shitty broken Mastodon doesn't show images properly". And they would still pressure Mastodon users to switch.
I'm not sure but I think that a similar strategy could work for browsers, using a web plugin.
But even if Meta decided that Threads is unavailable from browsers, it wouldn't be blowing one of Threads' legs off. There are far more mobile than desktop users nowadays; and if they want to EEE the Fediverse, they need numbers for that.
