I usually start with the comments. So many sites are dumpster fires of ads and/or trivial observations stretched out into blog-length essays. I want to know if the article will be worth my time/hassle before clicking through.
If I'm replying to a comment that isn't directly about the article, I may not read the article first. If I'm making a comment about the article, I read it carefully. But I don't often comment about the article. :-)
