Fred Cavazza has an interesting and link-rich post on Enterprise 2.0:

To make a long story short, it means using inside an enterprise the successful tools of web 2.0.

Please, do not sum-up this to internal blogs or wikis, this notion gather much richer fields and above all implies deep mutations which go farther than rolling-out new tools.

Also note the emphasis in this diagram of (1) user centricity (2) syndication (3) apis; it's hard to disagree with this though I expect that syndication, perhaps coupled with Atom Publishing Protocol-style push (also see our posts on GData), will probably remain far more important than APIs. We'll see.

On e-mail:

Internal communication gets more simpler: no more lost emails, stacked replies where someone is always missing in CC, doubles and susceptibility management (”I am the project leader, why am I only in CC?“). Everything is handled by the blog engine: publication, comments, archives, categories… Blogs are also a perfect match for new comers in a team which can have access to discussions history. If you are looking for a golden rule, here it is: if more than 5 person are in CC of your mail, than you better write a post.

This is one reason we've been working so hard on serious e-mail integration of blogging and  e-mail; people are going to remain "mentally comfortably" with e-mail for a long time and will usually be running an e-mail app or have quick access to one. In the BlogMatrix Platform, with a simple cc: you can move a discussion from the e-mail world into the blog + comments one.

Brief comments:

• Fred has to revisit his CSS to increase line spacing; I actually sucked the entire article into Word and reformatted so I could read the damned thing. On the other hand, I always do that.
• Fred is much more focused on the changes to enterprise culture than I am; years of working at large three-letter acronym companies garners a certain cynicism to culture change. My personal belief is that if tools are bottom-up useful and inherently culture changing, that's where we'll see the ball start rolling.
• Also note the mention of microblogging and "lifelog" (elsewhere called a lifestream), you know, just because ;-)
