Want to make friends, establish relationships and connections? Like others posts often. If I'm being honest, whether someone likes your stuff is kind of irrelevant. In these communities, your likes move others up the ladder. Plus it seems that randomly the person you liked is notified you took the second to click thumbs up. When I see that, I almost always take a quick look at their profile. If we have something in common, I'll dm them and who knows....we maybe be able to do something together. I've gotten a bunch a dm's from people just cause I liked one of their comments.
So. Take 10 seconds when you're in a comment section and click every thumb you can find. You never know.
#Quick thought - Like often, even if you don't really.
