Social media time travel

I wish there was a social media network to connect us to people from different times. And before anyone says "books", I mean in a reciprocal way. A Facebook-like service to communicate with others from the future, or the far distant past, or with relatives the way they were before we knew them. Or even with a friend who completely changed; to talk to them when they were different. It would ret-con the universe and completely screw up our timeline, but it would be so damn interesting and cathartic before time starts to eat its own tail and the aliens have to show up and fix everything.

The 1996 Room

I just woke up from a dream about a restaurant in which the main room was ordinary, while the one beside it included all the same patrons--but from 20 years in the past. Both rooms were lined with mirrors. The mirrors in the main room showed the reflections from the past, while the past room showed their reflections from the future (or, rather, the present). Most of the waitstaff had to avoid the 1996 room, but a few servers who were trained in time travel could work in there.

I told Mike about this and said, "That just worries me. In that dream world, not only does a waitstaff position require a college degree, but the job description also demands you be proficient in time travel?"

He responded, "The application reads 'Must provide own Tardis.'"

Dammit dream world, please do your job. I go to you to find alternate realities, not more exaggerated versions of this one!

Time-traveling and piracy

What if every single astronomically successful songwriter, author, or inventor is a time traveler from the future who ripped off someone else's idea, and we're living in the alternate timeline in which none of the original creators get credit for their work? (Then again, have they really been cheated if they didn't come up with it in this universe, and they're hugely successful from it in the other?)
