No. Not even slightly. Fifteen years ago reddit was still far bigger and more active than the fediverse.
Here there's barely any content today, back then I was regularly getting 30+ pages deep into reddit when I couldnt sleep most nights, and I wasn't even close to the end of that days content.
I bought a new netbook last year to watch stuff on as my old one from like 10 years ago finally fell apart.
I fucking hate the new Windows so much and I'm not techy enough to change the operating system to something better, so I barely use it as watching stuff on my phone is easier.
These are great till you live somewhere with shitty electric. On the days when my ecig takes 6 hours to charge I can't cook as the hot plate won't even turn on. Fucking slumlords.
Posting or reblogging a meme to/from a meme tag on tumblr, isn't something I'd consider 'talking' to anyone. Nor would a news article be, or anything else that I mentioned above.
A great many popular tumblr posts have no notes or conversational reblogs either, as they're just photos of cool looking frogs or memes or images of stuff like that.
If you really want to, you can make posts to the fediverse/reddit/tumblr/etc that are just you talking to yourself.
If you're funny, interesting or popular enough, some people might even come to talk to you on your post, or just read and upvote/reblog you.
If enough people do this, the algorithm picks it up and lots of people get to see you talking to yourself till other people join in.
And if it's a funny/interesting enough post, the content might even be screenshotted and shared across platforms.
What do you think is more likely to be screenshotted and shared across platforms: a funny/interesting conversation, or a really popular picture of a frog that has no comments?
And what do you think there is more of on tumblr?
Have you ever been on tumblr? I mean like just gone to the website and looked around?
How is reblogging a photo of a frog, a bunch of comedy gifsets and some current affairs news from a war zone, 'watching other people talk to themselves'?
Well sure, if you like the sound of your own voice so much, you can do that.
Or you could follow a buch of tags and reblog art, nature, politics, comedy, maths, articles, photos, gifsets and games.
And if you really want to talk to people, the reblogs, tags and notes are good places to get words out, and there are dms and asks too (if you switch them on).
Use the tooth brush and running water to brush your tongue clean, and spit a few times. That way you get a clean tasting/feeling mouth while not rinsing the suds from your teeth.
