with no end time to an auciton, I dont see the point. I would like to advertise but I am not going to bid in an endless auction.
I'm extremely sorry for the inconvenience. Auction for this space ends May 15, 2014, i.e. tomorrow, but I dont see an option to update the opening post accordingly. Please excuse me for that. It is my mistake.
I'd also like to mention that in April 2014 we received 0.5M+ pageviews as per Google Analytics.
This auction is only for the 468x60 ad space on home page as mentioned in the OP. But definitely other spaces on the site are also for sale and will be auctioned. If anyone of u are interested in any specific space, u may PM.
At this moment FXO's bid of 0.1 BTC is the highest.
