Touche on Ghostly blocking all Heap requests, didn't realize they did that. However, other sites still irk me like the Omniture cases. Is it so hard to confirm functionality before you use it? Plenty a corporate internet blocks lots of these JS libs/API's and if you're not writing fault tolerant code, folks are going to wonder why site X does not work and just use site Y instead.
