A lot of commenters disagree with the "no dating" and "no alcohol" recommendations. But how many of these commenters are men and how many are women? For men to reject a recommendation put forth in the interest of women might be self-serving and establishmentarian.
A tally of both the ayes and nays to those recommendations from women would be most interesting to me.
For the record, I'm male and I'd be fine with those rules even if they didn't make the workplace more supportive of women. I don't pick my job based on whether I can date at work or drink at work (as long as there's no policy against pursuing those things with colleagues outside of work). But perhaps I'm an oddball because I prefer my relationship with coworkers to be strictly professional by default, and only override that on an individual basis; however, the norm in tech companies seems to be shifting away from this (even outside SV).
