Grindr as with any other type of app/website that's geared for instant gratification (ego stroking or hooking-up), usually ends with disappointment. On-line conversations make it difficult to read subtle, non-verbal queues given by the speaker, and therefore doesn't provide an accurate depiction of the conversation. Some people communicate really well on-line but fall flat in face to face interactions. Hiding behind a computer screen relieves people of their inhibitions and allows them to act in ways or say things that they wouldn't normally. We've all learned that 10 inches in on-line speak, is really more like 5 inches - which isn't bad either, but false advertisement leads to disappointment, especially if you were looking forward to mounting a stallion, and you end up with my little pony! (Ha!...I slay myself!) I digress.
I agree with Bashful, in that one has as much of a success rate on-line as in the real world of meeting someone who is dating/relationship material - especially given the porn-star status bar that has been set, that the vast majority of us don't meet, and probably never will. I'm sure that in the beginning sex between Brad Pitt and Angelina Jolie was smokin' hot, and now it rates below the Denny's GrandSlam breakfast platter! Lets get real - yes physical attraction is what initially draws us in, but unless you have more to offer, such as brains and personality, you're doomed after the sex glow wears off.
So as long as one utilizes these apps/websites without the rose colored glasses on and the blinders have been removed, and the expectation of success has been set on "normal" mode, play safe, but leave your heart, jewlery, and anything you value at home.
On another note: Don't bring someone you haven't met first, in a public setting, to your home. I've read recently that there has been a rise in robberies, assaults and in some cases murders, where someone just invited a complete stranger to their homes - see Advocate.com, about a young man who was murdered in San Francisco - witnesses stated that they recall seeing someone leaving the guy's apartment building carrying a computer and a flat screen television, unbeknownst that someone had been murdered.
Listen to what your inner-voice is saying, or in some case screaming about a situation you're about to enter into - it just might save your life!
