It certainly is not that we don’t have enough content to post here or interact with because this /c/ supports crosspostung. All opinions will be considered.
Also if there is any new apps to add to tge megathread or anything to remove from it do suggest that too as i don’t want to make another thread for updating it as i try as much as its possible to keep it updated https://lemmy.today/post/6716339 .
You can’t do anything to encourage others to come here asking for suggestions. Visibility of the community will do that, which means more posts, but the only way I can see that happening organically is if you go out to each app developer that isn’t already posting updates here and ask them to do so.
There’s not much to do here beyond that, honestly. You can’t force engagement on a topic like this. People come, get the info they need, and leave. People that want to keep discussing the apps after they’ve picked one are a small percentage of users, mainly developers or enthusiasts. Or really picky people like me that are looking for specific things and waiting for an app to meet those needs.
Anything to add about my second question ?
