Best Practices for Building Scalable Information Architecture – is a post from old school trouble maker Terry VanHorne. Some great stuff for the geeky. IA is an area I am personally bullish on.

Site links for directory structures; concepts in IA – speaking of IA, hehe, I had a post on the Trail that looks at how Google can give site links for directories, not just sub-domain approaches. A small, but valuable post (IMO).

Will My SEO Company End Up Competing With Me? – Barry was reporting on a WMW thread where a website owner that hired an SEO, worried that they would some day compete with him.

Google Gains Try Again Button For Discussion Results – was an interesting development over at Google that does some dynamic query revisions when you bounce back to the original SERP. Will we see this expanded? Only time will tell.

Are you using microformats & rich snippets to increase clickthrough rates and traffic? – yup, I’m at it again. As any long time reader would know, microformats are something I am on about a lot. The WordTracker blog had an interesting post on CTR around them. A worthy read.
