Haha yeah, you are definitely right and I feel the same strange feeling. I guess we are so familiar and so used to the names, it’s a daily visit for us back then but it’s in a new world.
A lot of us came from reddit. I think a lot also expect it to be reddit-like based on the threads and comments posted here. Making the magazines is sort of welcoming people and making the bed for new comers, hoping this place will feel like home. Those who made tons of magazines might have been subscribers, readers, lurkers, and want their interests to be here too.
edit:
A microblog is more of a tweet rather than a group chat. A person is posting an announcement/microblog within the magazine and anyone can see and comment on it. In a group chat, it is for invited people only.
Yes to subreddits equivalent to communities and magazines. But magazines have microblogs unlike communities.
