3 dudes made this in 2 hours. If the lgbt community gave a flying piss about this it would have its own up in no time. If it is in any way successful you will have 8 clones by then end of the quarter. Their decision whether it was incidental or a premeditated stab at homosexuality is completely ineffectual in the face of online trends.
I don't think it was a premeditated stab at homosexuality. I just think it's wrong to say they didn't plan hetero-only into their code. They aren't attacking the gay community -- they're just selfish jagovs. Besides, they are basically making Grindr for Breeders.
So the LGBT community already has an existing app similar to the one in question, but this app is still a horrible affront to the whole community because they didn't include you? A business can choose to not target all markets; it seems they chose to lead the design in an area that doesn't need to compete with GRINDR.
