Are you thinking about infoaxe.com ?

Or maybe historio.us?

Yes, I think it was historio.us prompted the discussion.

Dealbreaker for me: Piwik cannot do page-specific stats.

Everything else was in Piwik's favor, but I'm going to have to use GA because of this one requirement.

They forgot:

1. Lively 2. Google Print

Also, Google Answers preceded Yahoo Answers -- they got that wrong.

From http://glinden.blogspot.com/2008/05/yahoo-builds-two-petabyt... :

Yahoo builds two petabyte PostgreSQL database James Hamilton writes about Yahoo's "over 2 petabyte repository of user click stream and context data with an update rate for 24 billion events per day".

It apparently is built on top of a modified version of PostgreSQL and runs on about 1k machines. In his post, James speculates on the details of the internals. Very interesting.

Adding a Y axis would immediately draw up hundreds of blog posts and academic papers citing it as a "benchmark", making various claims and hypotheticals about Facebook's infrastructure. Since we don't have access to the exact metric or method of measurement, the exact magnitude is arguably meaningless.

Also, since this has potential for FUD and Facebook-bashing, it's in their interest to not publish raw numbers.

Or they could just leave out the graphs altogether. As it is, they’re pretty much useless.

No it's not useless since it also includes yesterday's measurement for that same timeframe.

No context in particular :) Just an observation of how the "inertial scrolling" people are raving about on the new iDevices has a history deeply rooted in Mac folklore (Andy Hertzfeld was part of the original Mac team).

Also note mention of hysteresis and Floyd-Steinberg Dithering which are worth reading up on.
