Hashtag...Corned Beef? Cannabis? Conversation?

Another thought on #.  When I hear the word "hash" I think of corned beef and hash.  A not so wonderful dish my Grandmama Dolly liked to eat.  I ate it.

It was okay.

But not as good as her apple pie.

Also, "hash" brings to mind marijuana.  Or cannabis.  Whatever you will...

Or perhaps the phrase, "We still need to hash out the details."

But hashtag?

And speaking of #, why did it become the "pound sign?"  Why was it ever added to the phone?  What was the point?

I'm pretty sure the automated messages will soon sound like this:

Press 1 for English.

El primo dos para Espanol.

For twitterish press hashtag for any menu consisting of 140 characters or less.
