Suffice to say there is a big deep ocean of shit to actually worry about under the frothy surface layer we usually interact with, and this vote is definitely the sort of thing to haunt these congresscritters with when they come up for reelection, but it isn't actually a significant change from the sort of behavioral logging most readily accept from facebook and google.
It kinda' is, though. There's a fairly notable difference between a particular website logging and the ISP doing it. Hard to puzzle out a good analogy, but it'd be something like the difference between being filmed when you drive up to someone else's house, and having the roads you drove lined with hidden cameras.* Surveillance on the service level is a titch less of a concern than surveillance on the infrastructure level. You usually can choose services, when it comes down to it. ISP is not quite so negotiable, particularly if "without" isn't really something you can live with.
*And US wise, we've actually been pretty adamant in a lot of the places the latter largely isn't kosher even in specific areas with overt cameras, never mind everywhere, even for sodding law enforcement, much less ostensibly private companies.

... on related subjects, anyone know of a resource that breaks down the historical congressional voting record on privacy (or just specific policy areas in general)? Turns out it seems to be something of a pain in the ass to find summarized records of voting trends in that area. Or any data that wouldn't require digging through several hundred/thousand difference sources to just to have in one place, never mind actually seeing what the leans are.
