Maybe Lemmy is attracting old meme people and content consumers and not content creators as much. The main. Feed is 90% memes and near useless unfortunately. It is for sure turning to dismiss it as not a serious Reddit alternative.
So unsubscribe from meme communities for the moment if you don't like it. They're simply currently the most active communities at the moment. If you want more in-depth content, perhaps contribute yourself. I have been contributing on non-meme subs, and it's mostly been successful.
No need to get salty. I am just pointing out what first impressions are as when you are new you have no subscriptions yet and that means you are looking at the main feed which is 90% memes. If we cannot be open to criticism here, this community will struggle to grow. Especially of others are hostile.
