I just submitted a link about synthesizers, and noticed there’s no directly relevant tag. The “audio” tag is for posts that link to audio recordings, not for posts about audio technologies; and there’s no “music” tag.
I did a quick search and there seem to be a good number of posts relating to audio/music, which could benefit from this. Plus we have a “graphics” tag, so lobste.rs is unfairly biased towards eyeballs over ears!!!
As Niklaus Wirth said, the eyes are “the only high bandwidth interface to the human brain.”
As always: more tags, more filtering powers.
…and more work for submitters, suggesters, and mods.
