I actually started posting with musing.io only four days ago. In the comments and the blog feed section of the blog I have no way to distinguish the musing comments and posts from the steemit ones.
Although I haven't seen the logo on posts before but if the option is given, then I would like to use it. I use the steem blockchain and the Dapps on it quite heavily - Basically I use the steem based Dapps a lot and I can certainly appreciate any way to keep my content marked, based on the dapp it came from.
Totally agree my friend. I also am using the DApps a lot now so like to instantly see on my feed what I'm posting. Im attempting to use Steem as my only form of social media.
