Update on "Who owns my MathOverflow posts?"

Your post is not a tangible thing, and bears no concept of a single “owner” who could decide anything and everything concerning the post. Rather, there are multiple rights associated with the post ...

Is it worth editing old posts to add links for references?

Yes, this is totally worthwhile! Please do this. The value of a linked reference is far higher than the value of an unlinked reference; the latter I fear often simply go unconsulted. I go further ...

Are edits performed by external, non-SE robots allowed?

Just to give some background on this project: it's indeed something I'm doing on my own, independent of Stack Exchange. There are more independent 'volunteer' projects around the Stack Exchange ...

What to do with links to arXiv front end?

If it's been down for a few weeks it's too early (as you say) but a good idea to mention it now. Your query points to about 600 answers, this is a lot, so the hope, if it's once judged time to make a ...

Altering the question in a way that makes an answer obsolete

As Gerald Edgar said, the most common reason for this situation is that the answer reveals to the OP that they posed the question in a form that did not properly capture what they intended to ask. I ...

Any policies around Dead links?

I guess I usually act as follows: a) If I know how to fix the link (typically, link points to an identifiable paper), I either edit accordingly, or add the link as a comment (I might even provide 2 ...

Restriction on Number of edits

I probably should write a few lines about this, since the question was obviously a reaction to my edits. (But it will be certainly nice if some more experienced users share their view.) I consider ...

Proper protocol for edit wars

As a longtime Wikipedia contributor who has been around a lot of truly crazy edit wars, my advice is: never revert more than once even if the other person's edit is terrible. Instead leave a comment ...

How acceptable is prosemirror-math as an editor style for this site?

Personally, I find it less usable than the status quo, but better than the new editor proposed by SE. So if it is inevitable that we will have to settle for an inferior alternative in future, this is ...

edits with links to material under restricted access

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 (...

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 ...

Is it a bad practise to add details (limited) to some one's answer?

I think so. The detail is all there, even if spread into the comments; it's what they are for. If further expansion is needed, why not just ask the person who wrote the answer to expand it? But, as ...
