What is a hashtag?

A question from a reader recently showed up in my inbox. The question is “What is a hashtag?”  Coincidentally the question I received arrived at about the same time as the date many people will consider the ten-year anniversary of the creation of the hashtag.

Something that I have always considered to be an example of bad design and bad philosophy is the use of those stupid dots and asterisks used to populate password fields so that nobody can see what has been typed.
