Well I was wondering the very same thing for a while and couldn't find anything. So I 'd made some stats myself

http://charts-bfxdata.rhcloud.com

For now it's very alpha project, so keep that in mind . The site will provide some stats on Lending:

• A chart with the lowest lend offer rate since 17 dec 2013. ( this because the Api doesn't provide a method to retrieve actual lends taken, this will give an idea of the 'current' and historic rates on lends)
  
• Charts with the total lend offers and lend demands in USD, with accompanying tables (scroll down) similar to the tables you'll see when are logged in to bitfinex.com.
  
• Table with the sum total of all open lends on bitfinex with the average rate.
  

Besides lending info I've added some stats on BTCUSD and LTCUSD (see links on top of the page): market depth + trade history.

Please feel free to give me feedbacK at: bfxdata@gmai.com
