Dion Hinchcliffe (emphasis added by me):

But most organizations already understand that spreadsheets, presentation files, e-mails, word processing documents, and private databases are where much of the valuable institutional information is.  While centralized "big IT" systems do a lot of routine record keeping, the heart and soul of an organization in the form of corporate strategies, product development plans, project notes, key performance metrics, and so on is really kept in e-mail folders and user's directories.  And while some of it must remain under strict control, particularly in public companies, much of it is unnessarily — and usually to a fault — hidden, unreused, and unexploited.

I like this quote, as it ties into the "datasphere" concept we've been tossing around, which says that the way to a semantic web is not through data formats but through the HTML world we're already familiar with:

Discoverability isn't an afterthought, it's the core. 
Google and other search engines made the Web usable.  The enterprise has not caught up, largely because most enterprise information doesn't allow a hyperlink structure, and links aren't encouraged very much when it does.  McAfee recommends setting up blog and wiki directories as well as good enterprise search based on link ranking (which is what Google does to make the right information come up in the first few pages of search results.)  Enterprise 2.0 tools should also extract folksonomies and other structural information (from microformats and XML tags) into discoverability mechanisms like tags lists and clouds, making user organization schemes obvious, public, and emergent.  One easy trap to fall into is to assume your existing enterprise search will do the job.  It probably won't, so be sure that it's well integrated into your Enterprise 2.0 effort, perhaps by offering a blog or wiki search option. Provide your own search engine in the tools only if you must.

Forget Web 2.0, Office 2.0 Is About To Zoom

While all of us were looking at the social-networked Web 2.0 sites for consumers, business applications emerged as the next big AJAX market player. Of course, we've seen what 37 Signals is doing but there are some new names in the market. itredux.com is promoting the use of AJAX based solutions for network computing. As mobile too becomes increasingly ubiquitous, the small local footprint of Web Apps will make them a logical choice.

Writely's not the only game in town. iNetOffice has just released iNetWord Version 2 to beta test: try it here. I still think the real game is selling the app to organizations to run internally "turnkey"; results can be published to PDF and to blogs for searching; and no more rolling out and patching expensive Microsoft Office copies across all your PCs...

There's been a number of interesting posts about "Enterprise 2.0" (recently deleted from Wikipedia!). Dion Hinchcliffe captures the key ideas (bolding mine):

One of the big attractions of things like Enterprise 2.0 is that it articulates the potential of using Web 2.0 techniques behind (and across) the firewall for greatly improved capture and sharing of organizational knowledge.  Retention and use of the volumes of insight, facts, solutions to common problems, and other tacit experience that is normally lost when an employee leaves or changes positions is one major benefit.  And not only is Web 2.0-style information capture encouraged with Enterprise 2.0, but the application of enterprise search to relentlessly find it again.

and

Business information that would otherwise be hoarded en masse within Microsoft Office documents of every description, e-mails, and data files stored privately in user's computers, accounts, and home directories — thereby severely curtailing its utility to the rest of the organization — can and often should be easily opened up and shared.

There's also been a number of posts about barriers to adoption (Jerry Bowles, Dan Farber, Rod Boothby) of Office 2.0/Enterprise 2.0 technology. One thing I note missing is that no-one's really made the case that it's cost effective, that the amount of time spent "enterprise 2.0ing" information by blogging and sharing and so forth brings a net organizational benefit. Obviously, we believe it and once it's working everyone else will believe it (and wonder what the hell was wrong with everyone's thinking back in 2006).

The likely case is that many of these technologies will be adopted first at a departmental level, prove their worth and then work their way upwards, just like with Intranet technologies in the 95-98 period.

I was going to say I love Writely, but perhaps that's a little strong: I really like Writely though. Writely's an Web 2.0-style full text editor, available through a browser near you. The appeal to use this is very strong: I have MS Office on one computer at home that's gone on the fritz and I can't find anyway to transfer the license over. Writely, well, I can just use that anywhere. Another plus is that you can collaborate with others on the same document.

Unfortunately until a couple of days ago the beta-try-it program was closed. Not any longer -- you can go get your account now:

Google has finally cleared the backlog of applications to join the beta programme for the Writely online word processor and has now reopened the application to new users. There has been no formal announcement on Google although there is a mention in Writely's own blog, presumably to prevent a rush of sign ups.

[...] Writely, along with the Google Spreadsheet launched earlier this year, is one of the core applications around which Google hopes to create an online office suite - although the current version does not integrate with Spreadsheet. Last week rival Microsoft launched its own Writer online word processor as part of its own suite of Live web-based services.

I'm not sure what Google's business model here is, besides perhaps "p-ss off Microsoft". Perhaps they're going to wrap Writely into dedicated boxes that can be dropped into an enterprise, not unlike the search services they sell. 

I'm now doing almost everything except spreadsheets "Office 2.0" style: I use Google Calender, Google Mail, Writely and BlogMatrix for blogging and information sharing.
