Normal Googlebot pattern?

Hi folks,

In checking my logs I noticed I have been crawled by Googlebot 83 times thus far since beginning February. Quite a few hits (28) so far today...

Seems to rev up on the weekend for both bots..then go away completely:

Sat Feb 15th, 2003 16 <--- 64 bot
Sun Feb 16th, 2003 28 <--- 64 bot (so far)

My site got indexed in January- but just became visible with real searches end of January. Many of my pages could be considered reference pages.

So, is this a good sign that perhaps people are linking to me or is this just normal GoogleBot traffic on a typical small site (under 40 pages)?

Google does not yet show any of my backlinks and I know for sure I have had several with PR4+ since before it was indexed.

Also, which one is Deep and which one is the Fresh bot? I forgot. :(
TIA
