Google made a manual search for my site - should I be worried?

[extra]

G..... made a manual search for my site today.
Should I be worried?

As a newbie I think I've done nothing wrong. I made my site for the visitors and last couple of weeks I had (and still have) between 20-30% of the visitors coming back (only 15-20% before this).
My site has raised steady in the serp, and now I'm on top for many phrases (local search in my country).
A few weeks ago I had some G.... visitors that seems to inspected my site (this is only what it looked like to me)
Beeing on top freightends me as it's a long way to fall. And when seeng manual search like this I'm even more worried.

Should I be worried?

If you aren't breaking any rules and have a good site why worry? It may even turn out to be a positive. I've had visitors from the plex without negative results. I bet many have.

Thanks Atomic.
When new things happends I always want to know why. Specially as a newbie.
I'm sure the visits was OK and their search in Google was only a part of some control routines.

I bet Google employees use Google to conduct searches.

Does Google monitor the searches of its employees? Or only when they use the Tool Bar? :/

How do you know that they did a manual search?

If this is through your stats page, how would they show up as?

Would it be a specific ip address

It shows up as IP 72.14.193.66 as well as Google as IP owner. The address was Mountain View California. The strange thing was that I could se their OS as well as the browser (these two itemes is normaly shown as "unknown" when google visits my site)
The search was http://www.mydomain.nnn/widget.html

You shouldn't be worried unless your site has affiliate content.

It is also likely that the visit was an automatic hit, especially if the browser was faked to Firefox 1.5.0.7 or 2.0.0.3 and the referer was either empty or showed this: www.google.com /search?q=abc

Some hits from those ip's are related to Accelerator but not all. They can be seen in the logs of many sites.
