In rough order:
If we know who the person is we rehash briefly how much we like that person.
If we don't know who the person is- we debate/trash/defend that person.
Assuming it's worth talking about then we talk a little about the hike itself.
Those who hate FKT's jumps in to trash FKT's. So that debate rages and criss-crosses back an forth until those people move on or become interested.
Those who are mildly interested or confused about the whole thing ask questions, those get answered, those answers get discussed, and more questions persist.
The folks who generally only "tune-in" for speed hiking catch up with each other and say hi.
That usually burns up the first 4-10 pages of an FKT thread right there... eventually the attempt might even start!
If the event starts we hem and haw about that a bit... though most of the haters are gone by then... a few will spring back up and a page can be lost clearing that up.
Since there is literally absolutely nothing to talk about when you get a minor milage update once per day in a roughly 60 day event... the thread turns into the general FKT water cooler and anything and everything related to FKT's gets discussed and rehashed like a bunch of pent up fantasy football players watching the NFL draft.
If it's looking good then much like a bunch of typical sports nerds a spreadsheet will be created and minutia will be discussed in painful detail.
Assuming failure- the talk will still continue much the same and generally unaffected by the FKT itself for a good few weeks after- then those who tuned in for FKT season will move on or wait for the next one.
Assuming success- There still isn't much to talk about in the middle 2/3rds of the event.
If you're NOBO- you get a good start or you don't. IF you're SOBO... we hang on till about Maine Junction.
If you're NOBO- we tune in around Maine Junction and actually get hopeful if you hit southern Maine on pace.
If you're SOBO- It's mostly filler until the smokies once you cleared Vermont.
That is only from a spectator point of view... so to speak. There's some good days, or bad days... but if it is a success as whole you get through it more or less on track.
Finally several pages of well wishes, atta boy/girl, congrats and similar will occur. They will be sprinkled with a few comments involving a "Stunt" "Discgrace" and trail founders performing violent gymnastics in their graves... but mostly that will blow by in the shuffle.
This year I think we did pretty good thus far blowing through most of the preliminaries and even moved on to the money topic and a few things not covered before.
The haters were somewhat limited and that died down faster than usual. People were generally respectful and remembered there is a human and fellow hiker actually trying this at the end of the day.
But as far as that comment about five guys posting over and over- that's total BS
