I doubt it, but you could be able to make something like that with wpmu.
		
	 
	
	
	
 
		
			
	
	
		
		i suppose with the budget and the time when they opened their service that they use a custom code.  btw, wpmu is following general structure protocols, so a lot of other platforms look like it…
		
	 
	
	
	
 
		
			
	
	
		
		I’m betting they built it with Ruby on Rails.
		
	 
	
	
	
 
		
			
	
	
		
		MAN..  I wish they had a BuddyPress plugin that turns my install into a Tumblr like clone..  I especially like the  “LIKE/HEART” function and the “FOLLOW” function.  that would be sweet.
		
	 
	
	
	
 
		
			
		
			
	
	
		
		Thanks for the link.
Rather; what I mean is having a plugin that transforms a buddypress install to tumblr like system.  so that we can host it ourselves.. its pretty close… now…
