What do you think about Lemmy, so far?
I know this sounds nuts but something that may be helpful is adding in a "firehose" community that's connected across the boards, with anonymous posting (chat and links), like notabug.io had on their front page. This might be inviting to new users and ppl just wanting to get their feet wet here. Idk it's just a thought. And to prevent it being annoying, make it not show up in "all" or "local" feeds. Some ppl (myself included) enjoy posting alot bc its relaxing and fun but there's not always a good place for that.
