These are the same as each other. You will likely prefer `out geom;` at 
the end of your queries; it outputs all the information you'll need, and 
is more consise than the `out body; >; out skel qt;` that's generated by 
Overpass Turbo's default settings. They are completely the same as each 
other. `out geom;` gives the objects' tags and geometry in one step and 
is faster to type. `out body; >; out skel qt;` gives the objects' tags, 
then ""recurses down"" (i.e. looks up the underlying nodes that make up 
each way, since ways technically don't have geometry of their own), then 
gives geometry for those nodes in a second step. Further reading:

Whoever told you that is probably wrong. They're really the same.

Myself, and CitySketcher on the wiki, are both pretty experienced with 
the Overpass API, so feel free to get in touch with either one of us if 
you need more help writing or understanding queries :)

You can update your page on gemini with this info if you want to.

Also, the Overpass Blog has so much neat hidden information! 
https://dev.overpass-api.de/blog/index.html

Stack Overflow is pretty sparse for Overpass, so I prefer to read the 
published manuals and guides and blogs for help rather than 
searching/asking on SO. This approach means I also learn things that I 
end up needing later on, rather than merely answering a specific 
question.

Trial and error is your friend. Breaking complex queries (>10 lines of 
code) into smaller ones is your friend.
