The Fortune 500 Business Blogging Wiki - Updated once every few days on average, this wiki is an evolving directory of Fortune 500 companies with official public-facing blogs. As of mid-April 2006, only 29 (about 6 percent) of the Fortune 500 have external corporate blogs, according to the wiki.
The Link Building Wiki by TextLinkBrokers.com - All about how to drive traffic by increasing the number of inbound links to your site. Tons of tips here.
The SmallBusiness.com Wiki - Has a great small business blog directory with hundreds of links in 25 categories. Also has a nice page on business blogging basics.
The TechCrunch Wiki - Despite the enormous popularity and influence of the TechCrunch blog, its wiki is actually very small - but bookmark it anyway. Right now it mostly contains information about meetups where you can rub shoulders with business bloggers and tech bigwigs.
The Blogging Wikibook - Disappointingly small, but I keep an eye on it because it's located at Wikipedia's wikibook site.
Of course Wikipedia has a decent entry on corporate blogs and a whole category of entries about blogging.
I thought I'd close with a quick update on the BusinessBlogWire Wiki, where folks interested in business blogging can share and receive blogging wisdom. I've updated it almost every day since I started it last month and it now offers free information about the benefits of business blogging, exploring for business blogs, blog publishing tips and more.
While 19 users have registered, I alone have made virtually all edits. So please help me!
If you're interested in helping me build the wiki, let me know (easton A T knowmoremedia D O T com or leave a comment below). Also, please subscribe to the RSS feeds for the wiki's recently updated pages and recent comments so you can easily spy on our progress and pick up new tips and info on corporate and professional blogging.
