On Stack Overflow find the software, find a tutorial, etc. is off topic.
Questions asking us to recommend or find a book, tool, software library, tutorial or other off-site resource are off-topic for Stack Overflow as they tend to attract opinionated answers and spam. Instead, describe the problem and what has been done so far to solve it.
But I don't see that close reason here.
Here's a question that could be closed under reason, if it existed:
While this is a common beginner question, an answer tends to be a link only answer, as that's all the question asks, i.e.:
Here's the PPA: https://launchpad.net/~ethereum/+archive/ubuntu/ethereum
I suppose when this becomes incorrect, someone can edit it. But it also invites problems with people flagging it as a link only answer, and edit wars about whether some link is better or newer than some other link, etc.
Should we have a close reason here as the other sites do?
