The Fediverse is quickly changing and probably we will have access to more features, but right now, a few things should work:
- You don't have to create new accounts on different instances, in order to create posts or vote. It's just like Mastodon and other platforms that use ActivityPub.
- If an article might be interesting to other programming communities, you can cross-post them to !programming@programming.dev or other popular communities, such as !programming@beehaw.org
If you want/like/enjoy something, do it, don't listen to others. It's also OK to learn something but never use it, either for the joy of learning or learning new things and new ways of looking at things.
Perl was my first favorite programming language, I really liked it. my brain could connect with it easily(same thing wasn't true for other PLs). It even helped me understand other programming languages better.
My current favorite language is Raku.
