I attended a star-studded open source panel this morning, with Bob Bickel of Ringside Networks, Jeff Whatcott of Acquia and John Newton of Alfresco. The panel and audience members discussed adoption of open source specifically for social applications.

There was a bit of discussion on market readiness for open source in this sector. A comment came from the audience that Alfresco, the most established of the three vendors, started with an “easy target” – that is, replacing document management systems that were largely understood and seen as commodities. The same audience member noted that applying commercial open source to emerging social applications may be more difficult, as these are viewed as more strategically important for IT and management.

Ringside is really only just now getting started so it isn’t too far down the road in selling to enterprises, but Bickel came from JBoss and so recounted some of his experiences there with overcoming adoption hurdles at the application platform layer. Acquia is also a new company but it is attached to the popular Drupal project. Acquia hopes to help legitimize Drupal for the enterprise.

Other questions from the audience focused mostly on the complexity of deploying some open source tools (lack of documentation etc.) and licensing issues.

The issue of how little open source was represented at this conference, something I had also noticed, also came up. John Newton said he went from booth to booth on the show floor asking “are you open source?” He got few “yes” answers. Alfresco / Acquia were on the show floor along with a big Sun / MySQL booth but of the 52 vendors on in the demo pavilion, that was about it for vendors with primarily open source business models (a few like Socialtext and Jive Software dabble some in open source but it’s not their primary model).

It’s interesting that at a conference that was all about communities and user-generated content, the vendors represented didn’t have more of a focus on community-generated software. The emphasis in conference sessions and certainly among the vendors on the show floor was much more around software that is easy-to-procure and easy-to-deploy for business users…in other words, lots of SaaS.

Why? I met with John Newton after the panel and he said he thought it was just the vendors present, not a real reflection of the amount of social software currently deployed as open source. I think that’s true as most organizations definitely have WordPress, MediaWiki and Roller deployments but none of these tools were represented at the conference. (Aaron Fulkerson from MindTouch was there (commercial open source wiki vendor) but MindTouch didn’t have a booth.)

Jeff Whatcott also noted off-panel that he thinks the SaaS and open source models will advance in parallel in this market but there will eventually be a “come to Jesus” moment when organizations realize the benefits of community development and the need to have the flexibility to develop, integrate and customize this stuff. I agree that these two models will continue in parallel for awhile or perhaps more than awhile as there are likely to roles for both SaaS and open source in the social software (or collaboration) market for the foreseeable future.

Update: I neglected to mention in this post originally that John Eckman from Optaros did a wonderful job moderating this panel.  My oversight for not mentioning that.
