Database Organization - Best Use?

I’m just starting to use DEVONthink, and have dumped a diverse collection of information into the database: such things as OS X information and recipes (as in food). Is it really a good idea to keep such diverse information in a single database, or should I create separate databases for such diverse information? The lack of a File->Open menu choice seems to indicate that you don’t expect users to be switching between several files on a regular basis (though I guess it could be done via the Tools->Properties menu.)

What’s the best way to use this powerful system?

The only way to use multiple databases in combination with the Personal Edition is to use multiple DEVONthink-folders and to rename them before starting the application.

Anyway, adding a variety of information to a single database shouldn’t affect the results (it all depends on the way one groups the contents).
