-snip- I also don't want the left side of threads to look like a rainbow explosion, so I probably won't add too many additional badges, either. -snip-
too many badges are also not very good for this forum. But there must be some updates to 10th anniversary bitcointalk contest artwork badge, because this contest might only be held once and this is the last. But it still has to look simple and not make the left side of the thread like a rainbow explosion. 
I'd love to see a badge for 'official' accounts, similar to verified Twitter accounts.
Official account for bitcointalk members? good idea, Maybe there must be some criteria if this can indeed be applied, to mark the account has been verified as the original account without doubt.
