Hi everyone, I have recently started reading this site again after having had a break for a couple years.
What I like most about LessWrong (apart from the name), is that it contains so much good quality information about rationality, all in one place. And the posters maintain such a high standard of reasoning. One thing I would like to see more of on the site, though, is analyses of common human behaviour.
Also, it would be great to see some humour on here.
If you want to explore the community more, I recommend reading the Library, checking recent Curated posts, seeing if there are any meetups in your area, and checking out the Getting Started section of the LessWrong FAQ.
The Open Thread sequence is here.
