Unnecessary pleasantries waste time and effort in task-based conversations. Never start a request for information or help with a useless phrase like "Hello".
If someone has shared this with you or has this link in their profile, it means they won't be offended if you skip the pleasantries and get straight to the point. Do still be polite, and feel free to have social conversations!
Consider this conversation:
The most effective method of asking the question? Just ask the question!
Being succinct and effective does not have to be rude,
it demonstrates respect for the
other person's time.
