Here's an interesting problem I think I'm faced with.  A buddy of mine who owns a fantastic Ethiopian Restaurant here in Portland, OR is having a Jazz Dinner event.  I was going to post a note about it in my blog, but then I realized, that if I post a note about this single event, with the way that google and blogs work that my blog could theorectically (and easily) find itself HIGHER than my buddy in a Google Search for my buddies restaurant!  I know we've all been surprised to find ourselves high in Google for some queries...and certainly some larger companies have been "hurt" by bloggers saying "Company X sucks" in their blogs enough time that Google believes it's true?

Am I right, and can I indirectly hurt someone's smaller site by mentioning it here?
