From small seeds... I had noticed a huge improvement regarding lemmy posts and threads, before the US election, and then it all kind of went backwards.

But if you have any questions about anything - niche or otherwise, you should post them on lemmy, helping it to grow faster. Even if the answers can already be found in other community forums.
You should get specific replies to your question anyway, but also anyone coming behind you won't have to go to reddit or any other place for the answer. It requires everyone to help, but questions are the fastest way to grow in most cases. Not including the likes of subs that can post original content, A TON of reposts on them too, but some OC. But mainly asking for help with anything should get people with knowledge on the subject replying. With the idea that eventually many answers can be found here without having to go elsewhere. Start 'spamming' your genuine questions now..
