I do this now too, ever since I got a 705 last Christmas.

Before that, I was using a LiveJournal account and manually copying my stats from my bike computer(s) to a form and then maybe adding a little blurb about what I did/saw/felt, and then later adding a gmap-pedometer.com link once I figured out where I had gone.

Of course this didn't really allow me to track mileage or compile numbers.
