It's a slick site that includes a Google Map of where each whisky comes from, plus whisky-related event listings and discussion boards. They've got a business model too: affiliate links to partner sites where you can purchase whiskies.
What makes Connosr really useful, however, is its iPhone version of the site: if you're at a bar, this fast-loading mobile site gives you the info you need to pick a great whisky and review the ones you try.
If wine is your choice of drink, you might also want to check out Snooth and Cork'd.
What do you think: is Connosr an essential venue for whisky drinkers or yet another social network?
