I used Dave Winer's OPML archive to do a bit of analysis on his blogging at scripting.com. Some of the OPML wasn't well-formed and some of the blog entries were difficult to parse, but the vast majority worked extremely well.

• I found 70,692 blog entries and was able to parse 56,336, which is big enough of a sample size to well represent the source.
• He linked to 7,859 unique domains.
• He linked to www.scripting.com 2038 times.
• He linked to www.kbcafe.com 9 times.
• He linked to www.techcrunch.com 65 times.
• He linked to scobleizer.wordpress.com 27 times.
• He linked to scoble.weblogs.com 7 times.
• The top domain level blog was doc.weblogs.com, 268 times.
• Next was inessential.com, 157 times.
• He linked to his perceived enemies www.cadenhead.org 116 times, www.evhead.com 105 times, live.curry.com 51 times.

I uploaded some of the data to OPML Workstation in a proprietary OPML format. It shows everybody that has been linked to 6 or more times. Remember, the data is not exact.

I also found the OPML Workstation is linking to the OPML surfer. Thanks! I'll have to do some work on it (a link back to them) to justify that link love.
