There's a question on the front page:
I'm looking for any neat tricks/hacks you have come across in your careers.
I can think of two offhand:
A digital multimeter in continuity test mode can be used to check an LED.
An LED can act as both a source of light and a detector of light. With proper amplification circuitry an LED can be used as a photodiode.
which I believe doesn't belong. However, it has three upvotes, three answers, a lot of activity, and users are clamoring for community wiki status.
I think it's obvious that the question violates the Don't Ask section of the FAQ and fits the "bad subjective" category as laid out in the blog post on subjective questions. See also the recent Is there a place for opinion on the electronics.stackexchange? question.
Normally, I'd close this as "Not Constructive":
This question is not a good fit to our Q&A format. We expect answers to generally involve facts, references, or specific expertise; this question will likely solicit opinion, debate, arguments, polling, or extended discussion.
but I'm hesitant because there's so much community support.
The above guidelines are neither written in stone nor able to be derived from basic principles, but they're constant across all SE sites and seem to work pretty well.
I have two questions:
- Why is this question getting so much community support?
- Why (or why not) should this question be exempt from the above guidelines?
