Create 'Grindr Cogs' ...
When launching the app, have four cogs appear:
1) For hookups and s*x
2) dating and relationships
4) online chat rooms (social circles)
When you tap a cog, you only see guys near you who just want s*x, dates, friendships or just chat/networking.
This would be a great organisation tactic. Guys will not be offended by unruly d**k pics, or trying to date a guy who just wants to hook up and block after meeting. Those who just want to chat have a safe space to do so also.
You can pop in and out of the cogs anytime you like, but obviously you'd be reported if you're hooking up in the friendship or dating cog. Hooking up is for the hooking up cog.
Maybe this app will then be less of a circus, eh?
