Feeling a need to put porn in your presentation about CouchDB is a hang-up about sex. There are all kinds of activities that, while perhaps unobjectionable in and of themselves, just do not go well together.
I do not understand how so many seem to have lost the idea that context matters. What might be perfectly appropriate content or behavior at a party or a club in mixed company can be totally inappropriate at a business meeting, wedding, funeral, or conference presentation. Why does this idea even need explaining?
DHH was commenting that doctors, lawyers, and other professional groups have far raunchier conversations than programmers, and manage to attract women just fine. So my question is: do doctors routinely slip porn into a presentation about a clinical studies trial? Does a lawyer slip porn into his slides for his closing remarks? Does anyone honestly think either of those would go over well?
