TechCrunch's Michael Arrington has written an article called The Flickr Gunners
in which he examines three promising
new services that are gunning for Flickr's deeply entrenched position as king of the photo-sharing hill. His picks are
, the not-yet-launched Ookles
from Feedster founder Scott Johnson, and 17-year-old Kristopher Tate's
. Arrington doesn't go into a lot of detail with any of the
services, but these are definitely three Web 2.0 ventures to keep an eye on.
