I've been on a few for about 4 months.
I've never been good with the opposite sex in real life, and I've had some HILARIOUS depression and bad anxiety problems lately, so I figured this might be a better alternative.
If anything they've made me feel worse and even more crap. Hardly anybody replies, which is kind of...rude, and it's never nice to have the feeling somebody's just scanned your profile and tossed you aside. I thought 'we're all the same boat' would apply to a lot of people, but apparently that's not the case...
I may just pilot a shuttle into the sun and die alone.
