It’s at Wait But Why. Highly recommended for a high-level overview of the issue all in one place.
My personal take on the Fermi Paradox, or why we appear alone in the universe, is covered in the article. It’s a combination of we don’t know what to look for, and aliens are not going out of their way to visit us or communicate with us. I think Fermi’s original assumption that alien civilizations would build self-replicating machines to populate a galaxy is also questionable.
(If you’re interested in more on the Fermi paradox, some videos on this old blog post may be of interest to you. Look for the ones on SETI involving Seth Shostak.)
