I'm thinking of most of my posts being reposts
Why are you thinking about your posts?
I've attached no valuable thoughts to my most recent posts.
When posting on the internet you should mostly post valuable things or people won't listen to you. Nobody wants to waste their time reading the same thing.
It's reposts. I don't have time to post anything new.
Well if you don't have anything new to post, then try to think of some topics of discussion to contribute towards. You could always just be a lurker and read what everyone else is posting, sometimes it is enjoyable to sit back and watch others.
