Nothing is dead until it stops breathing and its heart stops beating, bbpress is opensource, if you like it as a forum and want it to continue then get coding, the wordpress codex says of opensource:

“open source – is simply programming code that can be read, viewed, modified, and distributed, by anyone who desires. …”

The next thing is promote it, if you have a blog do what I have done here: http://www.macmend.com/archives/114

If you just have a forum with no blog then use what I have done above as a sticky topic.
