I'm somewhat stuck in no. 1.
Not all posts really deserves to be responded to. I rack my head to find a reply after spending 5mins of valuable time reading a post so I wouldn't scroll past without a comment.
Reading LeoFinance posts even, things I barely understand.. I wouldn't even know where to start commenting.
The things I love to read are not really things and communities that make one so visible.
It's a lot more work than imagined.
