Welcome! Also happy to help with questions, though probably a lot of the really important questions are not the technical ones but the social ones such as "how do I make my reading page be full of interesting things written by interesting people?"
I mostly found interesting people by commenting on other people's posts (which, unlike Tumblr, stays on their post rather than being a separate post on your page) and then following other people who made interesting comments on people's posts. That means there can be an advantage to going back and looking at older posts -- usually from the last day or so; things seem to taper off a bit after that unless a really interesting conversation starts -- to see if there are new comments. Also, if an interesting conversation starts or a post looks likely to spawn interesting conversation, you can click the "track this button" (which looks like a little bell in my default style; I'm not sure how universal that is) to get notifications when people make new comments on it.
Unlike Tumblr or Twitter, there isn't really any way to see all the comments that a specific person is making -- but you can see their "reading" page using a link like http://brooksmoses.dreamwidth.com/read (or click the "reading" link on their main journal page) to get an idea of what the people they're subscribed to post. That won't include private posts that you couldn't otherwise see, and if they use a lot of circles to have specific narrower reading pages it won't show you what those are, but it is still pretty useful in finding other interesting people.
Finally, on things I have actual experience with: I'd note that my friend jenett does weekly "salon" posts which are basically just forums for people to have conversations in the comments. The most recent one is at https://jenett.dreamwidth.org/1794110.html, to give you an idea -- and you could either join the conversation there if it looks interesting, or you and other people reading this could start your own if the idea looks useful but there's less community overlap.
On things I don't have experience with, Dreamwidth also has communities, which are essentially communal journals where multiple people can post -- those were a big thing in fandom in the LiveJournal days and I believe still are here now, but it's been a long time since I've had time to seek those out. There are also the "interests" lists in people's profiles, which become links to lists of other people with that interest listed.
