We have the tag mega. I am almost positive that the OP for the only question so far is referring to the 2560 version of the board. Should we rename it as arduino-mega-2560, leave it because most people won't use the old revision, or add arduino-mega-original or arduino-mega-classic to refer to the original board?
It seems like the original version would still be used some. That's why I like the "original" and "classic" suffixes to the tags so a beginner Arduinoist (is that a word?) who wouldn't know the difference would just use the standard mega tag. However, someone referring to the vintage Arduino board would still be able to ask.
How should board revisions be handled? is not a duplicate because the Meta isn't simply a revision, it is just a "makeover" of a fairly popular board to keep the branding.
