No, stick to forks that manage to reach a self-sustaining level above “one or two users cherry-picking from an upstream repo as a passion project”.

My point is that a fork can be abandoned by users even if the project is still active.

Your point is worth thinking about it, audacity needs a critical mass of users. But does it have enough original users to keep from being considered abandonded already?

Edit: to be clear, other software is often used instead of audacity. It isn't as well known as say photoshop, or maybe even inkscape.
