Two points that I haven't seen highlighted enough in the rest of the discussion. The only (apparent) purpose of the userids in the permalinks is awarding Announcer badges. Badges and reputation may be fun, but they are just a game and they are not that important. If this is the only reason in favor of uids in permalinks, I think that the cons highlighted by ...

status-completed For reference, here are the pages that Google knows use the old domain. If people have strong feelings, they can fix those they want to and remove them from this list. For comments, a follow-up comment pointing out the new url will probably be sufficient. Done https://mathoverflow.net/a/28601/ https://mathoverflow.net/a/6408/ ...

I'm not a member of this community, so I'm going to throw this out as a suggestion and see how many votes it gets. Consider linking to isbn.nu, which queries a number of online booksellers and shows prices for all of them. (My current reading.) This is always my own choice these days, on Stack Exchange or elsewhere. Be aware that links to Amazon have the ...

I think having a hyperlink to a bookseller can be quite useful for the reader, and that's all that matters.

Below each question and answer, you will see a 'share' button. Click on it and get this: The url you need is right there, already selected to cut and paste.

There is a good reason for linking to a paywalled link. It is usually the official journal link. It is likely to contain the accurate citation information, it is likely to stay on the web for longer (as opposed to self-hosted paper by the authors), and it is ultimately the official version. Of course, if the link is just to a library link, then this is not ...

This Google search site:mathoverflow.net OR site:math.stackexchange.com mathoverflow.net/questions/31222 OR mathoverflow.net/q/31222 produces a list of posts on MathOverflow and Math.SE containing links to the question you mention. Actually you don't need both the "q" and "questions" form for the final search term, since in fact all the links provided ...

On my opinion, links with restricted access are legitimate and desirable when there is no free link to a particular book/paper. After all, this is a site for professional mathematicians, and majority of professional mathematicians have access to some math library which subscribes electronic books and journals. Moreover, in many countries university ...

It could be reasonable to collect some past examples of such proxies. This would help in assessing whether something like this is technically feasible. (And maybe also to which extent implementing this might actually be useful.) Also I assume that if something like this is implemented at some point, we'll need to prepare list of regular expressions for such ...

Privacy concerns are legitimate, even though I do not feel that one has any factual basis on which to make claims of spying or unethical behavior, whether on the part of individuals or corporations. I'd rather not take the argument in that direction -- in fact I feel that would be fruitless unless more information comes to light -- but simply acknowledge ...

The Internet Archive Wayback Machine allows you to save some web pages permanently as seen on at a given date and time. For example, I generated the following to save this page as it was before I answered: http://web.archive.org/web/20150322201116/https://meta.mathoverflow.net/questions/2193/stable-url-for-linking See the FAQ for the Wayback Machine for ...

I would link to some standard place like amazon where you can read the review and see the price without any hesitation whatsoever. Linking to some obscure bookseller, indeed, makes an impression that there is a reason for the choice (which may be the case, for instance, if the book is either available nowhere else or is much cheaper there). Anyway, the only ...

I've added a warning similar to what Martin Sleziak suggests: The warning looks for words1 that include the string proxy and later .edu2. You can see the regex I used along with some tests at regex101.com. It shouldn't catch examples of "proxy" found in the post body. Unfortunately, it doesn't pick up all listed proxy links nor does it rewrite the URL for ...

It appears that you are asking two separate questions. You express curiosity about where flurries of activity come from and also ask for a list of questions that link to yours. These are separate things. Even if you did build a list of all sites and other SE questions that link to one of yours, it would not have enough information to determine when those ...

Let me add another suggestion how to handle this - with already existing tools, without any need to implement something new. (It is probably not worth to create a separate question for this - I am posting this suggestion as an answer, we'll see from the voting and the comments what MO users and moderators think about it.) It is already possible to show ...

As of last week, we also check for .net as a possible way to complete a valid domain, so https://stackexchange.com/leagues/week/mathoverflow will work going forward.

An overwhelming majority of those who participated in the poll are in favor of modifying the existing system for obtaining links to answers. How does one proceed from here? Shall we put in a request to modify the SE software?

Go to the answerer's page and find the answer there.

I suppose I am stating the obvious but: How some links are rendered in a specific email client depends on that client. So if you want some added functionality there, it would be a new feature for the specific client, I do not think that much can be done on the side of Stack Exchange. As already mentioned in the comments, if you are sending HTML email then ...

Links to Mathscinet and other similar sources cannot be "fixed" to work for all. Mathscinet indeed requires subscription. The ways to use it varies from one university to another and sometimes depend on where you use it from. Some use proxies, others use passwords etc. For this reasons, I try not to use the links to restricted web sites in my answers. When ...
