I haven't published here in a while, but I've been writing and presenting elsewhere:

As open source comes of age and becomes mainstream, more and more job postings include "open source skills" in their requirements. But do you really want to hire someone who spends their time exchanging flames with members of their own community in public forums? Someone who greets newcomers with "I have forwarded your question to /dev/null, thanks" and other RTFM answers?

I'm amazed at how many so-called "enterprise software systems" do not embrace the Web model in 2010, making them way much harder and much less fun to use than they should be. I have recently started making parallels between this and music teachers, and the analogy seems to work. Don't ask where the parallel comes from...weird connections in my brain I guess.
