stiq.it allows users to 'stiq' private or public messages, called stiqqers, to their location, anywhere in the world. These stiqqers can only be seen by others at the same location, creating a 'virtual bulletin board'.

Stiqqers can also be upvoted or downvoted, which affects their position when ranked by 'hot' or 'top' instead of the default 'new' ordering. Only registered users can write, upvote and downvote stiqqers. Registered users can also connect to other users as 'friends' and make use of private stiqqers.
