I can get pretty deep into cannabis and the wide range of herbal vaporizers. I'm also in the long term process of making a board game for It's Always Sunny in Philadelphia and much of that show is at a forefront of my mind at any given time.

Otherwise, or rather, overall, I just am pretty decent at giving overviews. Making a PC build easy, some aspect of technology with repeatable steps, picking up on small details that can be utilized in some way (meta gaming etc). I was part of a lot of communities that allowed for an expiation and it was usually met with positive end results, which more than anything is what's important about whatever it is I'm sharing.

Ironically the only thing of mine that I don't like going into extreme detail on is audio related stuff. I'm a production technician for live events so I can run lighting, audio, video, the works, and I know my way around it well. But talking about signal chains or DMX sets is just kind of sterile. I like more brief tidbits, such as properly wrapping a cable to make your life easier, and things like letting it sit in the sun for 30-60mins before wrapping it.

Similarly, music production because it's just so far beyond the basic level. Unlike a computer where for some reason a GPU and CPU feel simple to describe (I suppose because they are an object), describing what a Saw Wave or what an LFO does to it is less tangible and tends to be met with a less engaging response. I think in this case it's in part the people it's been with, because I really enjoy learning this sort of thing from YouTube and many of those creators feel like a shoot-the-shit format where you're just hanging out and chatting about this cool noise.
