For all corporate marketers out there who’d like to keep track of the mushrooming number of blogs in Corporate America, here are three sources that you should bookmark.

If you can, please help maintain these sources as well, since it’s a wiki, wiki world where collaboration is the keyword.

1. NewPRWiki (go here)

Created By: Neville Hobson
Maintained By: Constantin Basturea.

Concept:
The Big Daddy of all these lists, the newPRwiki was the brainchild Neville Hobson and helps maintain thought leadership in the PR world and in the process also catalog a list of corporate/CEO/government/intranet blogs and podcasts, across the planet. What it is:

• a repository of relevant information about how the PR practice is changing
• a collaboration tool for PR professionals and people interested in the practice of public relations
• an open space where anyone can ask questions, post ideas, or start a project.

I’m sure many of you have heard of the wiki and the rankings it contains and you may have noticed that I used it to help me rank the Top 10 CEO Blogs, Top 10 Corporate Blogs as well as Top 10 Thought Leaders’ Blogs (via Technorati).

2. Fortune 500 Business Blog Index (go here)

Created by: Chris Anderson, concept by Doc Searls (history of the index)
Maintained by: Ross Mayfield (Socialtext)

Concept:
In response to Doc’s assertion that “the risks and uncertainties of public business blogging are so great that big companies only do it under duress, when their traditional corporate messaging has lost traction”, Chris Anderson helped develop the index with the goal of:

…looking at which of the Fortune 500 companies are blogging and comparing their past 12 month share performance with those that aren’t. If this theory stands up, the blogging members of the F500 will have underperformed the non blogging members.

Interesting… Where do we stand now? The % of Fortune 500 companies blogging has advanced from a mere 3% to a mere 4% (as of 12/29/05) to a almost-not-mere 8% (as of 10/05/06)

3. Fortune 500 Blog Wiki Project (go here)

Created by: Easton Ellsworth of Know More Media and Teresa Valdez Klein of Blog Business Summit
Maintained by: Volunteers (39, as of 11/9/2006)

As of November 9, 2006, 39 registered volunteers have published research on 40Fortune 500 companies. 24 companies have at least one public-facing corporate blog; in all, 42 public-facing corporate blogs and/or blog portals by Fortune 500 companies have been identified. Volunteers have either researched or signed up to research 95 companies.

Concept:
Most recently, I was invited by my friend Easton Ellsworth of Business Blog Wire to participate in project for building a wiki-database of Fortune 500 Blogs. Definitely a noteworthy addition to the existing Fortune 500 project, this one differs subtly in its goal:

…you will help others understand how blogs are influencing big businesses (and vice versa), why these companies are blogging, and how effectively their blogs are achieving corporate goals

Here is my spiel on why corporate blogging is important. Happy Corporate Blogging!
