I read this and was interested enough to do a bit more research into the topic, and found this writeup here: <a href="http://formulate.com.au/research/mad-libs-madness/" rel="nofollow">http://formulate.com.au/research/mad-libs-madness/</a><p>Unsurprisingly, context is everything, and for some things standard forms are clearer and win in UX. Some sites saw conversions decrease from using mad lib forms, some saw them increase.<p>A/B test it if you do this.
This seems potentially psychologically manipulative to me since the form is putting words in the user's mouth. E.g. the example in the article: "My name is -blank- and I'm looking for the cheapest auto insurance." Maybe price is not the user's only concern, but this sign up form says it is. It would be interesting to see if these forms can actually change the user's views. (Sort of like NLP tries to do.) I.e. does the user's prioritization of price vs customer service vs coverage quality get changed by this style of signup vs a regular sign up.
I didn't see this article the first time it was on HN, so thank you for posting the follow-up.<p>This is an interesting concept. We'll have to try using it for some of our forms.
Depending on what you're asking for, this can also be more clear than the traditional boring way (especially if there's no inline help text, say for spreadsheet column headers). It's not just for signing up new users for things.
I love it ... but I would also say that, in general, mad libs are good for creating shareable content :) People feel ownership of something after they've customized it, and crowdsourcing the answers make it easier for them to just pick some of the ones already there, for each field. A few people would add new ones and you would have to manually review them and add them to the pool for everyone else to choose from.
