No. A good blogger/writer defines himself with his content and gains status this way by putting his beliefs and ideas into his content. Introduction just seems unnecessary because you need to make a name with deeds not words.
Yes , your introduction post will be good for you
Write every thing you love &believe , and every one will love it so
Thank you for your invitation and good question
i think you should write a little introduction about your topic that what you are going to discuss its important otherwise it won't work that much.
No need. Your introduction should be posted in the "About" page.

depend on what you will going to share and how important it is
some ideas need introduction to be understandable 100%
