When editing posts, is it good or bad idea to remove introductions ("Hi, and I am new to here") and endings like ("Thanks in advance"), in addition to more important changes like multiple spelling errors and formatting?
Closely related, how about removing clearly unnecessary information? Fictional example:
This computer, located in my basement, next to ... is used as router/firewall. The problem is with firewall settings.
For example location of computer might be important, if question is about instability, which might be caused by environment or by software.
In my opinion it makes post cleaner and removes clutter, but on the other hand it removes something original questioner wanted to say.
Somehow related to Is it possible to "over edit"?
