We've pointed to Steepster as a social network for tea snobs, and Snooth for wine-lovers. Both posts were filled with cries for similar service for whisky fans, so we're back with Connosr. Trust us, it's all about whisky.
Connosr lets users catalogue, review and rate whiskies you own and have tried. You can share those reviews with friends and check out what they've been drinking, then add their favoured spirits to your wish list for future sampling.
The site has extras that make tracking and reviewing whisky even more enjoyable (if that's possible), like maps of distilleries, calendars of events detailing things like tours, tasting events, and whisky-centric gatherings, and the ability to browse whisky reviews via a tag cloud. Looking for a peaty taste with smokey overtones? There's a spot in the tag cloud and a whisky to fit your request.
Connosr is a free site, but requires a login for anything beyond searching and reading reviews.
