The ? (question mark) and ! (exclamation point) when combined so ?! usually denotes (connotes?) baffled incredulity[0] or something similar.
[0] http://en.wikipedia.org/wiki/Exclamation_mark
From good ol' Wiki P, "The exclamation mark is sometimes used in conjunction with the question mark. This can be in protest or astonishment ("Out of all places, the squatter-camp?!"); a few writers replace this with a single, nonstandard punctuation mark, the interrobang, which is the combination of a question mark and an exclamation point." ps: when Wiki P says 'a few' here please read 'hardly any'.
>For those who wouldn't click cause it's "Female Founders" - so far it's been just as inspiring as Startup School (even for me as a man).
I'm not going to put words into your mouth. Can you explain what you meant by this using a different set of words?
"I know this conference is clearly targeted to women, but it's interesting and inspiring to all (aspiring) founders, so I recommend men don't let themselves be put off by that"
Most of us are familiar with passive aggressiveness, though. Playing dumb in the face of it is one way of deflecting it.
