Congratulations, Verizon customer from somewhere in the vicinity of Potomac, Maryland, using Firefox on Windows XP and a screen resolution of 1280×1024 who clicked in from voxday.blogspot.com on the night of February 20th! You were my 10,000th visitor. Aren’t you proud?
OK, so 10,000 visitors in who-knows-how-many years isn’t much to brag about in the blogosphere. But, gosh darn it, they’re my visitors! 
Congrats, Jay. (I’m a LONG way from that myself, being very much a latecomer…but I’m curious if you have some particular sitemeter tool that you like. The standard logs from my host don’t seem to have that kind of detail.)
I use sitemeter.com. The biggest problem with it is that it misses some visitors, and I have no idea how many. I just know that every now and again someone will tell me they read something on my blog, but sitemeter has no record of them being there. It also won’t pick up on feedreaders. You might try Google Analytics. It shows much of the same info, but it doesn’t appear to let you see all the info on a particular visitor. It only shows that you had one visitor using IE, one visitor using Firefox, one using Windows XP, one using Mac OS X, but it won’t tell you directly that the visitor using Firefox was on Mac.
