I notice on a lot of mags, there is one or two people posting, and either 0, a handful, or quite a bit of upvotes, but no one is really engaging, most the time there are 0 comments.
I think in order to foster the growth of our community, we must try to engage more with the people generating the content, it's helpful and encouraging for them, and also a positive sign for people who are coming into the fediverse. I post quite a bit, and comments always make me feel like it was worth it!
Also, keep upvoting! Someone responded to your post or comment, and you're just grateful for that or agree with them? Upvote them! Engage! That's all :)
I think it's a matter of content type. We have a lot of links to interesting articles or pictures of memes with no additional input from the poster. Those make me less inclined to comment. I just tend to upvote/boost and move on.
I think for more discussion/opinions, people need a spring board to jump off of.
