I'm not very familiar with HN. A friend of mine told me they are people who are interested in good tool we give to the community. That's why I posted the news.
the link to the tool is giokr.com. By the way, the tool is interesting if you know what means OKR and you want to improve execution with this methodology (quite popular in successful tech company in the Silicon Valley). It's worth reading John Doerr, Andy Grove or Ben Horowitz on the OKR.
