Why is the SDMB membership declining, and what's the best way to add younger members?

Here’s some information on active users from 2019.

There were roughly 3,500 active users in 2019. There are roughly 1,200 active users now.

You can take a look at the Wayback Machine. That gives a snapshop of the front page of the forum. I haven’t looked at it since the change to Discourse. Looking at the trend, you can sort of tell when Google’s algorithm changed.

Based on what I’ve seen on other message boards, 107 new users in a month is super low. It depends if it’s true new users or if it contains spammers and return users past the 30 day mark, but even without that, it’s still very low.
