Google is showing a new type of display for forums in the SERPs, where they list a selection of forum posts related to your query. I think it's a great idea:
I've been getting a fair number of blog comments lately with link attributes like rel="dofollow" and rel="follow". Their purpose is to try to override the CMS' nofollow settings. Trying to override my website settings is extremely obnoxious. I immediately ban anyone who leaves comments like that.
I don't believe that search engines will start following links that have those made-up attributes on them, though it's an unknown because technically, an HTML element can't have two rel attributes. Do any search engines discard the 2nd attribute? (nofollow)
It looks like Google has just started adding additional information to results from forums in the SERPs. Notice right under the title below where it says:
5 posts - 3 authors - Last post: Aug 21

Search engines like Google and Yahoo are based on Unix (Linux or BSD). Unlike on Windows, filenames on Unix servers are case-sensitive. That means a file called INDEX.HTML is a different file than index.html.
Drupal has an SEO issue where URLs are not case sensitive. I'll explain why this is a problem.
This page was a test of Google and case-insensitive URLs as created by the Path Module.
Japan's cell phone technology is generally a couple of steps ahead of the USA. One interesting feature of Japanese cell phones is that you can take a photo of a special bar code with the phone, and the mobile phone will perform an action, like visit a Web page or send an email. If this feature were implemented in US cell phones it would have great possibilities for Internet marketing.
I use Wordtracker as my keyword research tool, but I've noticed a lot of inaccuracies in the Wordtracker numbers.
