Arguments to support the idea:

• According to browse.feddit.de, this is the largest community for showcasing electronics projects, the last post is almost one month old.
• People that signup to alien.top via the fediverserver portal will have this community as the recommended alternative to /r/electronics, but they will pretty much never see it if the community does not have any fresh content and will be more likely to lose interest.
• Despite the usual criticism of mirroring bots, the way that the fediverser tool works is showing to actually help interaction. In the past two weeks, I’m seeing an above average increase of subscriber and (more importantly) user count on communities like !main@selfhosted.forum, !homelab@selfhosted.forum and !emacs@communick.news
