Check out the last gadget on the right of my blog (scroll down). That's pretty cool right?
I took the other sitemeters down because I didn't know how to interpret them, but with this one it is at least plausible that each red dot represents a sentient reader given that there are only about 20 of them and I can "see" Tracy, Trevor and myself (and probably Greg). Obviously most of them are just passing through etc. But I still think its cool. Hello Latvia and Trinidad and Tobago!
I'd say that the number of subscribers in google reader is also a good measure. I notice Trevor has zoomed past me.
