is there a place for me if im interested in people's stories and experiences but not in depersonalized news and jokes and us politics? i dont want to post from the name of community but from my name, i dont want to subscribe to the whole community but to interesting people/topics

here to discover one more fediverse platform (i have a pretty active mastodon account: @ralen@social.linux.pizza) im interested in tech, specifically linux and other foss systems, like haiku, bsd, redox etc, other foss technologies and software, new hardware, specifically risc-v hardware (tho dont have any myself yet), foss android apps (i build crdroid rom for myself). im also depressed and socially insecure and lonely. also interested in languages (but can use only two - russian and english, and understand two more - polish and ukrainian). sometimes read books and watch movies/series. study software engineering in uni (finished second year)

so, how does lemmy works? i know mastodon is hashtag and subscription based, but i dont see any hashtags here, how do i follow interesting topics and avoid ones im not interested in? how can i make my post more accessible, discoverable here?

btw jerboa is great tho has some little inconveniences
