Inter linking

[Giorgio]

I have several sites in different languages, all hosted in their respective countries (as Google suggests themselves).

For big old Google it ain't hard to discover those sites all belong together (Analytics, Webmaster Tools, etc.) so inter linking them should not trigger anything specific IMO.

Do you think that inter linking my sites is a good idea (ie Dutch reviews link to German reviews and such) or do you think it is better not to inter link them? If you suggest not, please tell me why you wouldn't?

PS: Randy Ray, I am also very interested in hearing your opinion.
