How do you deal with being the only one posting in a community (aka "shouting into the void")?

I'm not gonna lie, sometimes it feels a bit lonely. I try to post on a few generic communities

• !interestingasfuck@lemm.ee
• !casualconversation@lemmy.world
• !movies@lemm.ee
• !lego@lemmy.world
• !map_enthusiasts@sopuli.xyz
• !comicbooks@lemmy.world
• !avatar@lemmy.world

Sometimes I can be the only poster for a few weeks. Makes me requestion the relevance of posting at all. I started posting to !pics@lemmy.world recently just because at least my posts are widely seen, and other people post there as well.
