I like the site. Although I suspect that the goal of the site (saving precious time by not consuming anything but the best) is contradictory to building a community around it.

Look at all the "social networks", they are procrastination maximizers. Rationally people want to save time, but emotionally your heart is where you spend a lot of time. So if someone is saving your time, you will thank them, and then you'll forget them. If someone takes all your free time in a way that is not completely repulsive, they will become your tribe.

Something similar is visible on LW. On one hand, we are complaining that LW is just another shiny toy for procrastination. On the other hand, if there is a week without too many articles (the best time to stop procrastinating and actually do something), we complain that LW is dying because of too much censorship or negativity or whatever. Maybe the best thing for most LWers would be if Eliezer would simply turn off the whole website for a month, and only display a text "stop procrastinating, go out and win; the website will be back on September 1st when all of you are expected to report your progress in a special Thread". But would they hate it? Absolutely. Also, they would simply spend the whole August watching kitten videos on YouTube and refreshing HP:MoR homepage.

The only way to build an online community is to create a site where people can procrastinate.
