ssh-keys

So far I've created a separate SSH key for each server I need to login to (for each purpose, to be more accurate). I did it out of a sense of security, just like different passwords to different sites.

Does having multiple SSH keys actually improve security? All of them are used from the same machine, are located in the same ~/.ssh, most even have the same passphrase.

So... should I give up the whole system and just use one SSH key for everything?
