Dear Google...
Why do people only write formal letters to corporations when they have a problem? It's like the college-aged child who only writes home when he needs money. I'd like to see more of this:
Dear Google,
How are things with you? I'm doing well, if you were wondering. Congratulations on your DoubleClick acquisition; it sounds like you really burned Microsoft's biscuits on that one! LOL What else are you up to these days? Just thought I'd drop you a line.
Have a good one,
Chris
P.S. What are you doing on Friday - want to grab some beers? I'll send you an invite on Facebook.
Come on, let's show our favorite mega-companies how much they mean to us with some no-strings-attached correspondence.

You're right, Chris. So, how's this:
Dear Google,
Thank you for the Desktop Search program. It's the best, and has saved me time (and my employer and clients $). I don't even use MSFT's computer and Outlook search.
Sincerely -- mostly happy with your services,
Mike Driehorst

Just about perfect, Mike, although I would suggest making an offer of some frosty cold ones for maximum showing of gratitude, but that's optional.
