I have often seen the removal of phrases like "thank you" that mostly newer users, especially 1-rep users, tend to append to their questions.
I even do this myself, mostly because it seems to be a common standard here. I have a speculation why this is done, but want your opinions or a specific reason for it.
In addition: How to justify the changes (in front of the new user) when the main part of the edit is the removal of the "thank you"?
I (hope I) never edited a question just to remove a Thank you. But I always take it as a motivation to improve a question.
I check the title.
Can it be made more clear? Can it be phrased as a question?
I check the body of the question.
Are there typos? Grammatical errors? Wrong capitalization?
I check the tags.
Is the question correctly tagged? Missing tags? Non-sensical tags? Maybe even an option for a tag-cleanup?
In my opinion, only fixing a Thanks in a question sends the wrong signal.
If someone still feels like the majority of an edit was invested in removing a Thank you and he complains, I'd explain that we like to keep a high signal-to-noise ratio. Meaning, we like it when what we read conveys a lot of information.
While a Thanks! can be nice, it distracts from the problem at hand and is simply not necessary.
The SuperUser way of saying Thank you is an upvote, and it should be applied to a helpful answer, not be appended to the question itself.
