If I look under your name and I see a badge for “artist with 500 uploads” for example, that is useful and tells me something. If I look under your name and see “llama”, “april fools 2030!”, “participated in the 8th of september orgy”, “monthly donator reward”, “artist with 500 uploads”, “all-time donator reward”, “some IRC quote”, “custom donator perk badge”, then by the time I get any useful information it would’ve been faster to just go to your user page to check your artist tag.
I guess “a couple” of fun ones can’t hurt too much. You’d need to be very careful in choosing the “couple” though, to make sure they’re appropriately special and don’t start a slippery slope of “there’s a badge for X, it would be good if we made one for Y!”.
