Is it possible you’re being overly sensitive? Your community doesn’t have a lot of content or discussion, in fact prior to your last post, the previous was 4 months ago.
In regards to downvotes, there’s pricks on here that think that All is a curated feed and vote accordingly. Sadly there’s nothing no one can do to fix that. All you can do, as a community leader is to post regular good content and engage with the members you do get. Building a community is always more about the people than the numbers.
