Thing is, if Titor was traveling to find his gizmo, he probably was not going to tell people exactly what he was going to do with it.
Maybe some database of hidden nuke material, nerve gas, old cold war stockpiles, secret bunkers, or spy weapons caches are backed up on some old tape, using an encryption program that runs on some Big Iron Mainframe from hell. You can build a virtual box, sure, but you need the hardware to know what to emulate. Do you use the little tiny box, or bring back a literal TON of big iron mainframe you snagged from a junkyard? ;)
If the ultimate goal is to bring down the last of the tyranny and rot hidden out in the North America of 2070 after a popular revolution, you probably don't want the top 1% of the 1% in your host timeline to know what you are doing. Better to drop some hints, disguise it as bullshit, and keep to the shadows of the conspiracy nut world.
If it was a more mundane goal of tracking down hidden caches of old mafia money, THEN it's probably safer to claim you're trying to topple a government. ;)
The name is a minor mis-spell of Titer. http://en.wikipedia.org/wiki/Titer a math term most often applied to this http://en.wikipedia.org/wiki/Antibody_titer
So you've got computers, anti-bodies, and viruses.
We can only hope it was something to do with computer viruses and not literal viruses like the 12 Monkeys sort. lol!
And as tradecraft, or just general bumming around goes, the harmless lunatic fringe is generally safe to hang around. Anthrocons, comic cons, sci-fi cons, hacker cons, various political loons like commies, larouchies, libertarians, greens, an-coms/an-caps(the last one not so much these days, but in the past) and the spiritualists, astrologers, american hindus, sikhs, buddists, quakers/friends, some of the more peace hippie/anarchist faiths like various brethern church/primitive christianity factions(link here to avoid confusion http://en.wikipedia.org/wiki/Open_Brethren).
If you are in for a bit more adventure, there are various subcultures that offer shelter for someone who might have dimension shifted hard enough to end up with a pocket full of invalid currency, IDs, etc. Or worse, you've slipped into the shoes of a "vanished person", or someone wanted for minor crimes, such as petty theft, fraud, grifting, bootlegging, hacking, etc.
These ones, you need at least some skill to blend. Working man's bars, bowling alleys, blues/jazz clubs, you have to more or less fit a type/class. Gay/LGBT type clubs, some are more open, some less, the more accepting a culture is on the gay issue, the more these places seem to stratify and get away from mixing of "assorted sorts". Don't drink/do drugs and there's a REASON for that, well, you've got AA/NA meetings all over the place. Coffee shops/health food shops/wiccan-new age shops, those all used to be sort of mixing grounds for various subcultures. Various churches/faiths/fraternal organizations, takes a bit more knowledge to blend, but generally a Mason is a Mason, A Jew is a Jew, and a Lutheran is trying to get through a service without yawning too loudly and earning the scornful looks of other church members. ;)
Somewhat higher risk, but more open ended as far as exploration, is to be a "displaced person". Bus lines, train lines, RV parks, camping grounds, airports, seaports, truck stops, rest stops.. All these places play host to people who perpetually travel, and may only have a series of mailbox addresses and storage units across the nation, or multiple nations to call home.
Can you weld? String network wire? Repair industrial machinery? Fix fried out PLCs? Do electrician work? Rig sound/stage equipment or dozens of other trades? Hell, you're probably on the road 280 days a week anyway. :D 24 hour gym memberships may be the only thing keeping you sane. Work out, clean up, go back to your cookie cutter motel, and move on down the road 3 days to 3 weeks later.
Or lower rent/different skilled, you've got roving carnies, gut out and renovation crews, pavement crews, migrant farm laborers, cell tower monkeys, door to door sales crews, missionaries of various sorts, political campaign road crews, etc.
Nothing like someone with $5k worth on greendot cards, starbucks cards, assorted gift cards, 5-6 cell phones that work better in different regions, nations. Then all the 24 hour check cashing cards for different chains across the US, a Washington drivers license with a passport endorsement, 4-5 state ID cards, stacks of loyalty cards, a suitcase load of hotel/motel soaps, generic products with store brand labels you never heard of.
At least knowing a small amount of something about how all these people operate can save you some trouble. Most of you aren't going to jump around too much. You'll never live to experience hearing about Dom Deluise dying from three different causes years apart. Never hear about IRA terrorists killing half the royal family on the radio. Never hear the Tracy Chapman 90s version of Desperately Wanting. And probably never live to see your favorite loon conspiracy theory happen in real life. Yeah, they recorded the WTC destruction in high def, lots of crazy stuff on TV. Interesting to watch for 2 months, then the economy hit the shitter for 5 years. The pentagon though, that was a bonus, slamming a plane into something with 4-5 foot thick reinforced concrete walls and built like the interior perimeter of an old Star Fort? Pointless, brazen, batshit crazy, but they got their global jihad.
Probably most are not going to be prepared to get on Facebook at some point, see lists of family and friends, and over a week or so, realize they're all complete strangers. Still, for some, it may someday happen. But, always plenty of people out there you can connect with even if you've walked away from your home timeline just a bit too far.
For those who think it's not a bad idea to grow up, live in the same town all your life, raise a family, grow old and die 30 miles or less from where you were born, this is NOT gonna be your thing.
Exploring different islands of probability the size of worlds, that's something more for people who easily get bored, and are drawn to the unusual. If Robert Ripley's material just got you more interested in the universe out there, maybe this might be something to try.
