Intuitive formulation of trigonometry? | hackerblues: My best trick for being able to derive trig identies from scratch is to use the complex analysis identity:exp{i \theta} = cos(\theta) + i sin{\theta}where i^2 = -1.As an example, lets derive the double angle formula:cos(2\theta) + i sin{2\theta} = exp{i 2\theta}= (exp{i \theta})^2= (cos(\theta) + i sin{\th... |

How can you encourage users to generate content? | patio11: You need to answer this question: what need does contributing a review solve for the reviewer?

How can you encourage users to generate content? | x3m: 1- Agree with others on paying students to write reviews.2- You need to improve your UI significantly IMO.

Your homepage should be immediately useful to the potential users/... |
How can you encourage users to generate content? | neilk: If you think of it in terms of 'getting content' you're doomed. At Yahoo they were always yammering about 'user-generated content' like it was 'free stuff we can slap ads on'. Maybe you don't mean anything by the term, but I think such terms do have the power to shape our thinking.People participate on sites tha... |

Why not make people pay using karma points for each submission to HN? | tokenadult: This is a good thread to put up as a comment in the Feature Requests thread.http://news.ycombinator.com/item?id=363 |
Why not make people pay using karma points for each submission to HN? | PJGNasty: Microincentives are great in theory. I agree. I haven't seen them successfully implemented in this context (though you could compare to an ebay seller rating).You would think someone would have figured out an effective method of user-generated content quality control. |
Why not make people pay using karma points for each submission to HN? | bdfh42: Seems like an unwelcoming system for new users when (I assume) what you want to tackle is the very small number of spam posts.A bad side effect could be that HN users might be reluctant to post interesting items that were only likely to appeal to a minority of their fellows. Technical items on web development r... |

Review my startup: Bill On Site | fraXis: You should have a 'free plan' option. I use Freshbooks for all my invoices and I used their free plan until recently. Their free plan really sold me because I was able to use it for 6 months to make invoices, and when I needed to do more, then I was more than willing to upgrade to a paid plan. |

If you want a premium theme, another $15 if you want to tweak colors, $5 customized emails $5/1000. More of a virtual goods approach rather than the hosted solution route.Also might ... |

Office lighting recommendations? | weaksauce: I like the natural incandescent lights(sort of full spectrum, basically an incandescent with a coating on the inside) not too much more per bulb but it really makes a difference to my eyes. |
Why not make people pay using karma points for each submission to HN? | BearOfNH: This would certainly cut down on the number of poll responses, and those pesky "Vote up if you like chocolate" comments. |
