My personal solution is to treat the URL of http://lesswrong.com/r/all/recentposts as my Less Wrong home page, since it appears to load all articles from Main and Discussion equally for convenient viewing in newest to oldest order without kruft.

I also use this; it would be nice if it were prominently advertised. I also learned about it from a comment a long time ago.

If I were to be charitable, I could say the front page appears oriented to people who aren't familiar with the site or the concepts behind it at all, and need an introduction.

I do think that having an introduction page is a good idea; when people hear about "less wrong" and punch it into Google, they should get a welcome page rather than a list of title links. But if someone's already logged in, they should probably get a list of title links rather than a welcome page. It should be possible to have lesswrong.com redirect to lesswrong.com/about if the person isn't logged in, and lesswrong.com/r/all/recentposts if they are.
