Try using some skiming techniques. Steve does a nice job when he writes his posts, using a clear structure and nice formating. Then, you can get a clear idea of the content of a post by following this procedure:
1) Read the title, section titles, and keywords in bold face.
2) Read the first and last paragraphs.
3) If the material serves you, go ahead and read the whole article (or print it for later reading).
This way you can select which articles to read in 5 minutes or less.
