No to be a bastard, but I disagree. The design is really off-putting. It instantly made me bounce off the site. If design isn't an early concern, just go for something boring/popular/obvious. Lobste.rs isn't going to get too many compliments for its design, but it also won't get many demerits either.

I say change the colors and don't do it in three columns. That's just my opinion. The site might be awesome, but really, the design made me bounce.

I'd keep the three columns at wider browser widths, but make that third column more useful than now. Something like recent comments or hot threads or a list of recent games that members are working on. Give some incentive for contributing maybe.

Why in the <<something>> didn't you just reuse reddit or lobsters or ??? Tons of existing agitator site bases...

Try researchfields.com -- HN-like site dedicated to researchers and grad students for discussing that sort of thing.

I've heard that the amount of sleep you need is a genetic thing. But is that true? Does anyone know what the main research articles are for that?

And has anyone ever significantly changed the amount they need by lifestyle changes (like daily exercise)?

I needed a few more hours sleep on days with a lot of exercise (hours long sessions).

Sleep hygiene helps. Lights out, blackout blinds, loud fans and notification sounds off, no TV in the bedroom. The sleep you get is of a higher quality.

I haven't done it yet, but reddish lighting for late evening is something I'm doing around the middle of fall this year.
