Round and round we go, and we're back to March. I remember when I first dug up this bug (that image on the right)... what... two years ago? Maybe it's time for me to retire it and try to find something new. Maybe.

Today we have a bunch of stories from across the net, including Matt Cutts on Nofollow, CSS floats, analytics math, and more.

• So some one asked Matt Cutts about sites that only link out with no-follow. His response? Nope. Google sees nofollow as a useful tag, and thinks that trust is going to take a bigger role in shaping how people choose to link to others.
• David Gray explains how encyclopedic content can help your link building efforts. His examples? Stuff like the Apple iPhone page, oddly...

• A List Apart has a guide to working with CSS floats. Beyond the normal use of float: left/right, they discuss some of the more complex behaviors and use.
• Mobility Playground has a really rad post on building interactive maps with raphael.js. It's surprisingly simple.

• Two from our friend Stephan Hammel today, and they're doozies. The Math Behind Web Analytics.
• Next up, part two which is even more important: understanding mean, trend, min-max and standard deviation.

• Six revisions discusses the elements of responsive web design, such as grids, images, and options of different "views".
• Smashing has a guide to technical web typography. Very cool.

• Mashable has an amazing animation illustrating how users on Facebook reacted to the Japanese earthquake/tsunami.
• Politico has a very cool post on the politics behind ICANN.
