I was planning on going to SES this time around, but I just had too much work to take time out for it. Thank goodness for all the SEO Bloggers who provide great coverage of these events. It's not quite the same thing as being there and the networking and parties can't exactly happen though a blog, but it's better than nothing.
There are several blogs that have great coverage, but the best and brightest are linked from Search Engine Land's industry conference page (thanks, Barry). You can browse by day and then they have links to the best coverage of each session. Good stuff, Maynard!
