@Jason: I still have some diaspora ones from last year's FOSDEM, thanks! just trying to figure out how to best make use of the limited real estate on the laptop cover:P
As for laptops, I've started going to the "just stick them partly on top of each other" route because otherwise you run out of space. Need to be creative. Scissors also help to get rid of useless white space!
when I was in Jolla I had several Jolla stickers on my laptop :P I think i'll put at least one of the smaller RH stickers. actually I should get some ManageIQ stickers made, as that's the project/community I'm working with :)
