I thought this was a joke, but then he puts it right in his profile:
> PLEASE READ PROFILE. While some people use LinkedIn for "networking" and advertising their "personal brand," I use this site exclusively as a dating platform. If you are intelligent, attractive, female, in or visiting San Diego, and perhaps a bit out of the norm, I might be interested. Send me a message and invite me out for a drink! (and please make it clear you are asking me on a date) All non-dating related messages will be ignored.
But at the same time seems like it is a failed platform for him too:
> UPDATE. LinkedIn is too full of faux career climbers and not enough dating opportunity. Follow me on Instagram @georgehotz
