I have recently switched a bit on this. When thinking about what to upvote, I do not usually upvote unless I actually feel like replying.
I am just trying this out, but so far I am liking it. Of course i only give small upvotes percentage-wise.
Mostly doing this because I want to expand my network simultaneously. I do give some upvotes without reply, but that is the exception. At some point I may change my mind and go back to doing it some other way. 🤣
