Few informations are worth mentioning:

• As usual, this list is a weighed average of multiple rankings: Google page rank, Alexa rank, Technorati rank, Google hits, average number of comments, and Twitter rank.
• Only blogs dealing with (some) generic software engineering topics are allowed. This requirement resulted in the removal of three blogs from this edition: Paul Graham (no software development topics), Rough Type (no software development topics) and PragDave (posts are only about Ruby).
• I also removed a couple of blogs that didn't have any fresh content (= less than three months old, or anything later than November 2008).
• There are 19 new entries on this list. Some of them did not participate in the last edition, because nobody had told me about them at the time, which accounts for some very high new entries.
• The most remarkable change in this edition is Signal vs. Noise, moving from #67 to #5, which is largely due to their Google page rank having been upgraded from 4 to 7 since last time. Quite an achievement!
• Some other great performers in this edition are: Regular Geek, Mike Cohn, James Bach, Software by Rob, and Agile Software Development. I congratulate them all!
• Unlike last time, I did not include FeedRank in the calculations. The FeedRank statistics turned out to be more erratic than Alan Greenspan's economical predictions. So I discarded them.
• However, unlike last time, I now included Twitter rank in the calculations. Micro-blogging is a logical extension of the activities of many bloggers. Therefore their performance in micro-blogging is now part of the overall blog ranks.
• You can click the names in the Author/Twitter column to find and follow blog authors on Twitter.
• If you want to be included on this list, then send me an email and make sure you earn high ratings on Google, Alexa, Technorati and Twitter. Please note that I only track blogs with a Google page rank of at least 3. (And there are just three blogs with page rank 3 on the top 100 list. All others have page rank 4 or higher.)
• There is an OPML file available if you want to import the complete top 100 list (+25 extra) into your feed reader.
• There is also a spreadsheet available with 200 blogs, incuding the individual rankings on Google, Technorati, Alexa, and Twitter.

Here is the full list. Enjoy...
