I think it might be worthwhile to compile a list of super common errors new developers (or old developers) often experience when working in DM. I think it's probably apparent that a lot of our users use the same reference material when they're learning, which is why we have so many similar posts on the code problems/developer how-to sections asking about the exact same problems every year for the past who knows how long.

Trying to work with an uninitialized list.

Setting an atom's x/y/z values individually simply not working under a great deal of circumstances.

Saving your mob wholesale and then loading it back up doing things you don't understand (due to how the key value works).

I think it'd probably be most beneficial to simply have a single sticky post that'd act as a repository, and then just have the list of common problems and links to satisfactorily resolved examples of said problems. Preferably the simplest resolutions that explain the entire problem. That way we don't have 1 sticky per common problem.

I don't know how well this would work, since you can't really rely on people's code being the same as other people's, but I think if focus on properly explaining the principles behind what was wrong with the code rather than just posting the proper code, we can at least cut down on the "spam" by a decent margin.
