The trouble with that is that in all supporting browsers, the first 
thing people will get when visiting OSM is some sort of prompt. Also, I 
can imagine visiting OSM, starting to find where I want on the map, then 
noticing "Oh, it wants to know where I am", clicking "Sure, no problem" 
and being taken _away_ from where I wanted to look.

I think a "Find Me" button is better UI.

"Find Me", when clicked, scrolls to the appropriate place and adds a 
marker. It then, under the covers, keeps asking for an updated location 
and moving the marker if necessary, but does not scroll the map unless 
"Find Me" is pressed again.
