Since Macworld ends at 4, meeting at Moscone 4 hours later seems silly. Also aren't photowalks more fun in daylight hours with things open and people around? I'd recommend moving it up and wandering over to MacCamp at cnet by 6 to continue the discussion... or starting there and wandering off.
A few related items of possible interest on Friday Night in San Francisco. Fray Magazine is having a launch party & signing at The Booksmith which is at 1644 Haight St (between Clayton and Cole) so perhaps a bit far to walk - but then again it would both go through and end up in some very photogenic parts of San Francisco.
In any case I do wanto go on the photowalk - and I want to stop by the Fray launch & signing - ah the joys of San Francisco (not to mention that the Crunchies are happening in SF Fri night as well)
Maybe someone can email raines to see about a possible cross-promotion for this event.
My Annual closeout meetup at RedWoodRoom is at 10PM so I probably won't be able to make this event :(
