I'm not a big user of it, but I find sequence diagrams to be a great help in keeping the (RoR) design focused on simple, well-named objects with clear responsibilities, and well-formed messages and data passing between them.

In a previous career as a data warehouse architect I was a big user of data flow diagrams -- they were all I needed for ETL documentation.
