I like that you can search by keyword, industry or even just keywords within each category. It's also easy for me as it has all my contacts in one place so there aren't many steps involved when contacting someone through this database! The only thing about RSMCD was its lack of social networks integration - not sure why they didn't include those features but maybe that will be added at some point? Currently we are using RSMCD primarily because it gives us quick access to our contact information without having to manually input data into other databases (e.g., LinkedIn).
