Nice to see some people are still using this.
You know what I don't miss, hashtags.
A great thing about open source projects is that you can file bugs/issues directly, I wish more closed-source projects had an "open issue" system.
If only such a platform existed, where a project could track all its issues but it isn't a source code repository (i.e not just use an empty GitHub repo for its issue tracking).
Several projects I use simply take user feedback via email or social media and that probably isn't the most efficient.
