@luka Well, thanks for the instance! I choose this instance because the url is short. 😆
I think mastodon still have emptiness problem. Like for example, when I join, I don't know who the account that interesting to follow. Especially when you join small instance. Really want to use mastodon as my main feed source, but it seems there is no news media using mastodon now, so I currently use mastodon just as a platform to express my thought.
You can find people with similar interests by using a big instance's tags via url like this: https://mastodon.social/tags/php
You can follow people by clicking on their avatar and then on their profile use "remote follow".
Also: paste the url of a single toot public page (click on time-link of the toot) into search bar to boost, star or reply without following.
