Given that Microchip acquired Atmel a couple of years back, should we merge the two tags?
Let's not merge them just yet. One of the good points Lundin brings up is that the tags shouldn't necessarily be targeting a manufacturer, but a product line. Many people have used the manufacturer (Atmel) as a proxy for the product line (AVR), and I don't want to lose that information through a merge.
I think a synonym is a good idea (e.g. no new atmel tags), but let's not merge them yet.
