I don't always find links distracting. I agree with my peers' comments that time spent in academia encourages me to cite my sources. Reading a post with no reference to anything outside itself seems like a rant. Or it might be confusing because you may not know what the author is responding to/need more information. Linking tells the reader that the author is engaged with their topic and lends to credibility.
For me, letting links speak is the most difficult part of writing a blog post! Probably because I hate reading other bloggers' posts and having to follow links to figure out what they are talking about! I tend to link to something I specific refer to or respond it, like another blog post. I find it difficult to link when I want to explain a term or concept that I think is essential for understanding my post.
