Personally, I strongly dislike this guideline. I reject edits that do this on Stack Overflow and any other SE site.
When you ask a question here you're asking complete strangers on the internet to help you out. I would argue that saying "Thanks" is not just a formality, but a show of basic human decency. There is nothing wrong with being polite.
Now, overly long waffling introductions such as:
Hello and salutations, and good morning to you! I hope you are having a nice day and are doing fine today! I am a third-year student at the university of Aberdeen. I am currently learning to program C and C++ and am using the "Vim" text editor to do so. I really like Vim because it's very neat and cool! It's much better than Emacs if you ask me! I tried Emacs once but didn't like it very much, hence I am using Vim (or do you need to spell that as VIM? I don't know?!). Anyway, onwards to my question that I would like to proposition on this wonderful site that is part of the Stack Exchange family of sites: [...]
is doing nobody − least of all the author of the question − any favours, and should indeed be trimmed or removed altogether. As should overly long waffling thank you notes:
Thank you for your time and attention, it is greatly appreciated that you are willing to spend your resources to help me out with this problem I am having. I will pray to Yahweh tonight if you would like to, but please say if you are not a Christian (such as a Muslin, Jew, Hindu, Atheist, Agnostic, Humanist, Sananist, and so on) and I will not pray because I respect all religions! My uncle was bitten by a Moose once btw. LOLLL!!
Or, for that matter, meaningless signatures thanking the Kemal Atatürk.
But I can't recall seeing any of this here on a regular basis. Mostly, it's just a "thanks" or "thank you".
Is it really that distracting?
Do we really want to take away people's very human, natural, and polite response of saying "thanks!" when being helped out?
- As a child, if I didn't say thanks my mother would make sure I would say it! I think the same counts for the most of us.
Is it really worth kicking a page to the front page just for this?
It is surprising to many users, especially new ones. Is it really worth offending people over this?
- In the early days of the beta I've seen at least two users leave the site over removal of "thanks" with comments to the effect of "pfff, same autistic crap users as on Stack Overflow, fuck this".
It is not uncontroversial, even on Stack Overflow; see the original thread about it. Other sites (like TeX or EE) seem to have quite different guidelines.
To be clear, this is merely my personal opinion and not "policy". I just so happened to come across several of your suggested edits; all of them were constructive (thanks!), so I clicked "Improve edit" and added back the "Thanks" for reasons outline above. I believe I rejected one which only changed the capitalization of "perl" to "Perl" (I would consider neither to be "more correct" than the other) and removed a "thanks" as "no significant improvement".
I have no interest in going around the site adding back "Thanks" that were removed by other editors/reviewers, but when presented with a review task, I'll actually review it by keeping the good parts, and removing what I see as the "bad parts".
