absolutely they would. Not all time travelers have machines that can take them thousands of years into the future. Most designs only go to the immediate future...couple months, years, etc.
So yeah, you can easily make the assumption they are here now and have been in abundance.
Time travel has so much novelty attached. In reality it's a natural and easy thing to do. once ya get over the novelty you find time travelers everywhere. It's just a social faux pas to say you are now, cuz of the toxic skepticism and mental illness label stigma applied.
If you're not willing to disclose everything about your time machine, adventures, schematics, photographs people don't belive ya. So that shuts most up. Kinda like aliens that are garrisoned on earth in normal day jobs, the novelty drives people insane when they admit they're an alien. So again, people with extraordinary abilities, tech and experience shut up.
In my experience humoring these people with long lasting patience and manners really makes them trust ya and open up. Forums are notorious places for jerks. Indulge everyone and listen. TONS of people wishing someone would listen at length to their story without proof. Nobody does. It's why most don't know any secrets.
soon as you say 'where's the beef' they leave. People really have nothing to offer these people other than fear, humiliation, unwanted attention, and possibly endangering their life. KNOW YOUR PLACE.
If you had something to offer them like an exchange of valuable technical knowledge, other time traveler contacts, healing tech or whatever then they will value your relationship other than frivilous conversation.
Of course there's scammers, everyone gets scammed when they listen to everyone. Hazard of the job, however you will find not everyone is and you'll get a gem who gives ya proof.
Rule is: Friendly relationship first to establish trust, trade valuable information, proof last.
You'd be really shocked at how lonely these people are and absolutely no one then can truly trust to share their experiences. Num7 is right, this was a great idea, unfortuantely these subject topics attract the outliers of society who act like children. That scares away the people we are trying to attract. Take the subject matter seriously and act with integrity at all times. Treat this place like a temple.
There should be a 'rules of conduct' pdf here...so we don't scare away timid time travelers.
If anything a completely private forum probably would be best, Num7 get on it. hehe.
I mean the people here who know really juicy things, keep it to private convos or through other ways to communicate.
