A couple of points re @dbuzz
The 280 character limit is to align with Twitters character count. You're right about the pictures being included in that limit, which is a bit of a pain. You can shorten the links though with https://dbuzz.link/ or https://bitly.com or many others.
Re. the max 1 HBD payout, that is just the default max. payout. You can change that up or down. It's good to asses the quality of your Buzz before increasing the 1 HBD limit though, as per the pop up message you get if you do try to change it.
