A user recently asked the question, Gem `semantic_navigation`. What do you think?. Is it acceptable to request that people test your program?
No, that's off topic, there's no actual practical problem to be solved, and it's a bit of the open ended / opinion / discussion-y flavour.
A vastly improved version of the question that would include the essential parts of the question in the question's text would probably be on topic for Code Review Stack Exchange. I've posted a comment:
Hopefully OP will respond positively.
That question is Not Constructive in giant flaming orange letters.
It's, first of all, a poll -- is anyone using this thing? -- second, asking for opinions, third, doesn't actually have a problem that needs to be solved, and for a bonus point, is entirely dependent on offsite code that (conceivably) could disappear any moment.
