What kind of comments make you visit someone's blog? I usually check the blog of every person that comment my posts (I don't receive that many haha), because I think that if they find my post useful, is because, maybe, they read/write about content like mine, but I haven't had much luck finding interesting profiles through commenters, which make me believe that they are only looking for attention/views/followers.

What I usually do is going to the profiles of people which write content I like, and look at who they're following.
