* A thorough rewrite of the follow_me routine. The total cost is 38 extra gzipped bytes, which is all right. (topic.js)

  ! Fixed error message in IE8 when loading a page; this was due to style.position not accepting dummy values in a DOMReady context. Go figure...
  ! The feature now works properly when resizing your window. Sounds easy, but it wasn't.
  ! Fixed positioning of the first comment in blog posts. It was badly broken.
  ! HOPEFULLY, I've fixed the Chrome bug of infinite heights forever.
  * Faster page initialization times, due to internal optimizations: min-height is no longer used (this was the root of the infinite height problem), .poster divs are no longer touched, and floated divs only get updated when needed.
  * Severe performance improvements on scroll when hardware sticky positioning isn't available (up to 10 times faster). I went ahead and removed most of the jQuery calls, opting for native JS instead. IE6/7 never supported follow_me in the first place, so there weren't too many issues to fix.

@ For the record, follow_me still looks meh in IE10, even though it works fine in IE8. That's because their smooth scrolling gets priority over page reflows. Not my problem, and I don't care enough to check if this was fixed in IE11.
