Depends entirely on the project, of course. But putting up demos, preferably as web pages, if that's not possible as a binary, tends to be a great way to show the world what you're doing. Open-source of course makes it easier (just throw it on github). Subreddits, irc, HN, and forums make great channels to get people to look at something. Another good approach, but that only works if you're near a big population center, is to find a relevant user group and do a talk there.
