Well, Dwight (who is not all that evil) provided the spark, and the Ten And Only Ten meme is spreading and mutating quite nicely.
Some observations:
Jeff Clavier had a hard time whittling things down with a blogroll as large as mine, and he also starts up a variant based on podcasts: 5pods. I would most certainly include Israellycool on that list when I write it, although can one truly separate a podcast from a blog that it's highly integrated with?
Syntagma ignores the "don't include any blog you write for" rule I imposed on myself. I was wondering how long it would be before I saw that variant.
60k demonstrates another theory of mine... as you limit the number of blogs, you start to fill "roles" for each blog. Sort of like position-players in limited-roster sports. The Albuquerque blog he lists fills the "local scuttlebutt" role.
France! Interesting to see if anything has been lost in translation... not from the Stygmata instance it seems.
Jarvis makes observations about A-lists. He's looking at the elephant from another perspective, but will he do the exercise?
Blogfresh picks up a few entertaining sites like PostSecret and 10by10. Hrm... information vs. entertainment? Infotainment?
Fancy Storebought Dirt shows that people's tastes change over time with his mention of Michele, Cuban, and Olberman. Yeah, I've noticed that a few have altered or dropped off. There's two on my lists that's likely not to be there next time I do this if they continue going the way they're going. (And I consider Althouse and Instapundit redundant - redundancies in a limited list? Interesting.)
Suburbia 75 lists his own blog. If you're going to an Island, which I never really stated (I assumed that you're in a workplace with limited access and your RSS feeder can only get so much in, why ingest what you already know.
Odd. Where's the Lileks?
Guy Brighton breaks his list up into multiple category lists. Hrm... cheater! Now try to condense them into a single list and see which is the best fit for each role.
Pederson lists Flikrblog, which reminds me of an also-ran of my own list - Trillian's developer blog. If you're really into a product, you're likely to watch their developer blog, right? Or are you willing to pass on the blog and just wait for the downloads to pop up?
Austin Pauls observes that the list is subject to change at a moment's notice. Ah... let's see what 10 this person lists in a few months if they do it again. Also, I notice Mark Cuban's site there... someone else said they had dropped it over time. Are blogs seasonal in nature?
Inoperable Terran posts, but without links. Yeah, I could Google Search "Dr. Frank on Suicide Girls" but I'm a lazy man at heart.
How this thing is spreading and mutating is utterly fascinating. It makes me wish I'd stayed with Biology and had an opportunity to create my own pathogen to mercilessly release into the wild like those Hollywood movies.
Oh and I need to remove IMAO from my list in the next iteration because I've started posting one item a day there and I don't include sites I own or write for.
