Get more gay men on Grindr
Lessen the hookup nature of the app, so that more non-h0rny, quality gay men join the app for friends and dates. Sponsor events in major cities. Hire ambassadors (college students, bartenders, young people, etc) to promote the Grindr brand. Hand out free Grindr merchandise/apparel at gay bars and Pride events. Advertise in local gay publications and social media. Let's get more gay singles on Grindr!
why not just join another app, instead of trying to redefine this one?
Plenty of other apps for that.
