The 43 Best Blogs
site is a mildly interesting wiki of 'Bests'. The reason is I think it's only mildly interesting is it's sort of like the writings you'll see on public restroom walls -- a collection of entries by anyone with no officiating, no explanation of opinions, etc. For example, if your Mom wanted to list your blog in the #1 spot on the best blogs list right this second -- she could. So, it's all in fun, but there are a number of excellent choices on the list that are worth subscribing to.
Why the number 43? As the site says, "Add a blog, delete a blog. The answer to Web 2.0 is '43', so please leave the site with the same Zen as you found it."
