In practice though, unless you're posting somewhere that will be seen by many people all at once, the odds of someone joining during the 30-60s someone else is joining are acceptable.
Of course, it's far preferable to be able to talk to prospective players *before* they join, but it's generally survivable without.
(Unless the game does crash, and you've got more than one impatient little shit that's spamming the join button as soon as they think the server crashed.)
