Programming language authors really need to learn how to make a website. Look at Ruby's: http://www.ruby-lang.org/en/
No long explanations about what it means for Ruby to be a dynamic, object-oriented language. I don't have to read its author's paper or book to get it. Just a short code snippet to show me what it looks like and several links so I can learn more.
Only a small number of the language websites listed on the emerging langs camp site have any code on them, and that includes those with maybe just a couple of lines for an edge case scenario.
I guess a bunch of those languages are highly academic and the meat is in the implementation as opposed to the syntax. But language developers need to start putting some effort into the non-code parts of their projects. I'm not going to get inspired to pick up a new language by bullet points. At the same time, I'm working on my own language project so I know it can be challenging to use just the right code to give the best first impression.
Although true, many of those authors are too busy with improving/fixing their compilers.
E.g. the D language doesn't have a very modern looking website atm., but someone has took the task to update it recently. It's not up yet since the community is trying it out.
