In the last few months we’ve seen the rise of location-based mobile networking the likes of which some people envisioned a while ago but few executed on.
What’s required is something which is vague about location (“close by” is good enough), has real people and provides open conversations to prevent abuse. Something like a location-based bulletin board. Mixer, on iOS, might just be that app [download it here].
Mixer is a new social mobile application for iPhone that lets you converse with people on a location. You log in via Facebook authentication (preventing aliases and scammers) and can start a threaded discussion linked to your general location. Users can post text and photos to the local feed and others can comment.
