Best Comma

I have been noticing loads of people lately signing emails, cards, etc.  with "Best, Phillip" or "Best, Suzie."  Has this been always happening or is there an upswing?

For some reason that I won't fully examine here,  "BEST comma" is like a hair suit for me or, worse, a belly button tattoo.  I hate it.  HATE IT.

Maybe I don't understand from where it derives, etc. but it drips with insincerity.  (And one could fairly argue "Well how sincere is Sincerely, comma?"  And they would have me.) 

But still BEST, argggghh!  What does it mean?  I send you my best, but I am too lazy to spell that out?  And if I do, what best am I sending to you? My best wishes?  Okay, but best wishes for what?  A happy life?  A new throw rug?

Best regards?  And what does that really even mean 100 years after it really meant something?

Clearly "best comma" is used for when you don't know someone well and it is a business-y thing.  But when I get that I feel looked down on or dismissed.  My own issues, I know, but best comma just seems to suggest that you have to hit send fast and get right on to something way more important.   It has a "tag your it" or hot potato quality to it. 

Couldn't we just pull any words out of our asses and sign it that way and it would have as much meaning, but more fun?
