4/18    If a conference deadline gets pushed again and again (from 4/14 to
        4/18 to 4/26), does that mean it's a bullshit conference?
        \_ It's reasonably often that, for a reputable conference, this
           happens _once_ for any given deadline. I'd guess it's not
           impossible that there's a rare instance of it happenning twice.
           Any more than that is quite suspicious... but then, really, if
           you've never heard of the conference before and neither has
           anyone else you talk to who works in the same field, it's in
           all likelihood bogus. Academia is too small of a world to not
           notice such things. And if the "conference" makes its name by
           spamming every damn person in the field several times a month,
           the rest shouldn't even be a question. And no, "SCI" is not the'
           only name that these scammers go by. Do a little digging online,
           and you'll notice that there's upward of a dozen fronts that
           these assholes advertise under. -alexf
        \_ All other things being equal, this is a bad sign. But there are
           legitimate reasons to do it (publisher becomes more flexible,
           many people ask for extensions and the organizers feel it's fair
           to give one to everyone, etc.).
