"#" ....... Pound Or Hashtag?

A few years ago, someone decided that this symbol “#”, which so many people have always referred to as ‘pound’, should be re-named as ‘hashtag’.  Although popular opinion suggests that the ‘twitter’ generation may be behind this change, I think I will opt to continuing using the word ‘pound’.  What definition do you apply to “#”?  The poll at the bottom of my ‘home page’ will remain open until August 7^th.  Go ahead and vote.
