If you're a lighttable user, and you already know how to use it, please join a few communities, maybe answer a question per week, just help people out. Here are some communities that need more people:
The subreddit, www.reddit.com/r/lighttable (this subreddit is deserted, here I was, thinking the Sublime Text one was deserted...) The google discussion group, https://groups.google.com/forum/#!forum/light-table-discussion Join the IRC at #lighttable on irc.freenode.net
If you're a passionate light-table user, please spend some time on improving the documentation! If you wrote a plugin, please write a blog post or make a screencast on how you did it, or live-stream the making-of! If you really like a feature, write an article, write a blog post, anything! Please write some blog posts, please write articles. This editor has so many hidden features I can't figure out because no-one is talking about them. If you don't have the time to write blog posts, or if you're at work and you're not allowed to stream, or anything else, even a simple tweet will spread the love <3
Light-table would be a revolutionary IDE if only it had a community. Chris (the author of light-table) has the right idea of what light-table should be, because it's based on a talk that changed the way Chris, I and many others think about programming. Chris however, made a crucial mistake from the very beginning of the project, he never invested in a community.
