I don't totally understand microblogging

Microblogging is something I've always wanted to get into but never have really been able to feel comfortable doing. Maybe it's because I feel like if I have something worthwhile to say, I'll use many more characters than Twitter or a similar site would allot me and have the chance for people to actually see what I wrote if I post it somewhere where I know for certain people would see. If I have some passing thought usually I'll just bring it up to one of my friends in conversation. I guess the idea of Twitter is to get input from people outside of your social bubble when you have a thought. But how do I make that happen? The other thing that bothers me is that there's no easy way to access your old posts without looking them up specifically. What if you post something embarassing and forget? My blog site manually edited in HTML is pretty easy to sift through.
Ever since a certain professional rich guy who happens to be very dorky took over Twitter I've felt a bit better about not being into that type of writing because now I'm practically locked out of Twitter unless I use xcancel.com, meaning that I can't see the posts of the people who I wish I could write like.
I guess what I'll never really get into is the consumption of "content" like candy like TikTok/Twitter/similar websites encourage. I know this topic is *extremely* hashed out by now, but TikTok has been especially weird to me ever since it came out because I don't even understand how anybody could enjoy consuming content like that. TV is similar to TikTok in a sense because you're presented with content in a way where you have very little control over what's being presented. But the difference between TV and TikTok is that while TV shows are designed to grab your attention for an extended period of time, TikTok clips are intended to grab your attention for around 30 seconds max. I don't understand how one of my family members is content to just flip through their TikTok feed without sparing even 2 seconds of time to look at what they're sifting through. I suppose YouTube is the link between TV and TikTok when it comes to the amount of attention people will dedicate to each piece of "content". For instance, a long TV show episode is 30-40 minutes, the average long YouTube video is about 10 minutes, and now the average long TikTok is probably about a minute.
All in all, I think I have a better attention span compared to the average person from Gen Z, but I think it could be better. I'll just be a blogger instead and post on Mastodon whenever I have something to say that I think isn't worth posting as a blog.
