MetaFilter on Photo Sharing Site 23

23 | MetaFilter Metafilter on photo sharing site 23. " It's like Flickr, a lot like Flickr--and maybe better. Better at some things. Stories. Upload limits. The layout. Ordering prints. They are doing things from the beginning that Flickr worked a couple years to figure out in the first place. Flickr of course is way ahead of 23 in numbers (people and money). Does it make sense to challenge that lead? (And to do so with an overt knock-off?) If 23 provides a better service, should they lose out for being second to the party?"
