A lot of being tech savvy is understanding how the world works. The basement dwelling computer guy is a myth. For example, do you know that MIME isn't intrinsic to a file? It's like 100 pages of documents written by an American nonprofit about how to compose the string of "text/plain". Basically how to write words with a slash in it. How you use it is up to you. Half of the other things we do on computers are just because a Swedish nonprofit said so.
