For any lurker out there: a lot of it is just mental. It can be a hurdle to get over the first few times, but once you start posting and getting responses it feels more like a conversation than a feed, and you can get more out of it.
I lurked exclusively on Reddit because there were too many people to be able to talk to anyone (there’s a Yogiism for you). It’s all just a series of comments there.
So give it a chance, see if you like it some more. There are plenty of nice, knowledgeable and talkative people here to meet.
