When my profile is viewed from my Mastodon-profile it automatically adds a named field ”Blog” with a web version of my micro.blog field (for me this is social.torb.no). I feel kinda bad about this automatically being put there. I consider micro.blog to be my social media (or I suppose microblog), but I absolutely do not consider it to be my main blog (my main blog is www.torb.no) and I hate that this is how it’s presented like that. It’s also rather pointless since your’re already in Mastodon, so you already have my posts available.
Suggestion: just remove this. It’s not a default that makes much sense. If someone wants a link to their web presence of micro.blog they can just link it in their bio.
