Maya architecture overview

This is where I found that Maya has over 600 commands and 900 nodes.

I know lot of people are making function that are not needed, because there is already some command or flag, which can deal with it. Similar with API classes. It is really worth reading Maya docs, searching for a suitable command or googling it or wondering there and often something usefull can be found. Because lot of these "gems" are not advertised at all. But it has a lot of potential.
