The attempt to leave a comment on a blog post that begat a blog post.
I only wanted to to leave a comment on Bernie Goldbach's blog post and when I choose to leave a comment using my Facebook login credentials, this is what TypePad asks for...

The last 2 are the most egregious. Really TypePad, this is a blatant identity grab. Do you really need all those permissions just so I can comment on a TypePad blog? TypePad is going on my Facebook App blacklist.
p.s. We have reached an inflection point in the world of blogging when it is easier to write a post on your own blog than it is to comment on another's TypePad blog. This is as it should be :-)
